Alternative Terms Proposed for Libertarianism or Anarchist Libertarianism (Other Than “Anarcho-Capitalism”)
I re-consulted the four specified articles on stephankinsella.com (and related posts), the Carpio chapter, Cato materials, writings by Hayek and other libertarians, plus the attached PDF of Legal Foundations of a Free Society (3rd printing, 2025). The book (preface, foreword by Hoppe, and chapters such as “What Libertarianism Is” and “What It Means To Be an Anarcho-Capitalist”) consistently uses libertarianism, anarcho-capitalist, and anarcho-libertarian (or “anarcho-libertarians”) as the core descriptors. It frames the philosophy as a “private law system informed by libertarian principles” and a “free society” grounded in self-ownership, property, contract, and rectification—but introduces no new alternative labels beyond those already covered in the blog posts. Hoppe’s foreword reinforces Rothbardian natural-law/natural-rights anarchism without proposing fresh terminology.
Plain List of the Terms (by Themselves)
- Voluntaryism (or Voluntarism)
- Cooperatism
- Private Law Society
- Consensualism (or Consensualist)
- Market Liberalism
- Kritarchy
- Agorism
- Panarchy (or Panarchism)
- Polycentrism (or Polycentric Law / Polycentric constitutional order)
- Aparactonomy
- Anarcho-Libertarianism (or Libertarian Anarchism / Anarcho-Libertarian)
- Free-Market Anarchism (or Market Anarchism)
- Co-existentialism
Detailed Descriptions, Summaries, Origins, and Links for Each
Voluntaryism (or Voluntarism)
All interactions must be voluntary (no initiated force/aggression), often linked to the non-aggression principle. Coined by 19th-century individualist Auberon Herbert; revived in modern libertarianism by Carl Watner et al. Overlaps with anarcho-capitalism but sometimes viewed as broader ethics. You note its imprecision (e.g., “voluntary” under duress) and prefer clearer consent-based terms.

Cooperatism
Rules enabling peaceful cooperation and division of labor by minimizing conflict over scarce/conflictable resources. Tentatively proposed by Henry Hazlitt (The Foundations of Morality, p. xii). You endorse it positively as a framing that highlights libertarianism’s cooperative benefits over “anti-capitalist” or state-focused rhetoric.
Link: https://stephankinsella.com/2009/06/the-new-libertarianism-anti-capitalist-and-socialist/
Private Law Society
Law, defense, adjudication, and governance supplied privately via markets/contracts, no state monopoly. Strongly associated with Hans-Hermann Hoppe (who prefers this label). Equivalent to anarcho-capitalism but emphasizes institutional/private-law mechanisms. The attached book’s preface explicitly calls for “a private law system informed by libertarian principles”; Hoppe’s foreword aligns with this.
Link: https://stephankinsella.com/2022/12/the-state-is-not-the-government/ and https://mises.org/library/idea-private-law-society
Consensualism (or Consensualist)
Genuine owner consent required for resource use/actions, rooted in property/appropriation rules (beyond mere non-coercion). You propose/favor it over “voluntaryism,” tying it to conflictability/conflictable-resources analysis for true conflict-free cooperation.
Link: https://stephankinsella.com/2022/01/on-conflictability-and-conflictable-resources/
Market Liberalism
Free markets, individual rights, entrepreneurship, and minimal/no government. Promoted by Cato Institute as their philosophy label (economic freedom + civil liberties). Builds on classical-liberal tradition; not strictly anarchist but overlaps.
Link: https://www.cato.org/books/market-liberalism (Cato’s 1993 book)
Kritarchy
Governance by competitive judges via precedent-based law (no central legislation/state monopoly on lawmaking). Proposed by Juan F. Carpio as empirical/historical refinement of Rothbardian statelessness (e.g., Brehon Ireland, medieval Iceland).
Link: https://propertyandfreedom.org/books/rothbard-100/carpio-rothbard-statelessness-kritarchy
Agorism
Counter-economics (black/gray markets) and voluntary exchange to erode the state, leading to stateless free-market society. Developed by Samuel Edward Konkin III as praxis-oriented strategy within anarchist libertarianism.
Link: https://stephankinsella.com/2009/06/the-new-libertarianism-anti-capitalist-and-socialist/
Panarchy (or Panarchism)
Individuals choose their own legal/political systems voluntarily (exterritorial/personal law), no territorial monopoly. Coined by Paul Émile de Puydt (1860); revived by John Zube et al. Compatible with anarcho-capitalism but broader on jurisdictional choice.
Link: https://stephankinsella.com/2009/06/the-new-libertarianism-anti-capitalist-and-socialist/
Polycentrism (or Polycentric Law / Polycentric constitutional order)
Multiple competing centers of law/governance (private courts/arbitration) without a single state. Discussed in libertarian scholarship (including your 1999 paper on knowledge/calculation/conflict/law; also Randy Barnett, Bruce Benson). Core to anarcho-capitalist models.
Link: https://stephankinsella.com/2020/05/knowledge-calculation-conflict-and-law-1999/
Aparactonomy
Stateless, voluntary “nation” with cultural cohesion, meritocratic diversity, and self-defense under a constitution-like framework. Proposed by Kai H. Kayser.
Link: https://stephankinsella.com/2009/06/the-new-libertarianism-anti-capitalist-and-socialist/ (your update)
Anarcho-Libertarianism (or Libertarian Anarchism / Anarcho-Libertarian)
Anarchism grounded in libertarian (Rothbardian/Austrian/Lockean) property ethics and rejection of the state. Straightforward descriptive term you frequently favor as clear/sufficient. The attached book’s preface explicitly uses “anarcho-libertarians.”
Link: https://stephankinsella.com/2022/12/the-state-is-not-the-government/ and preface of Legal Foundations of a Free Society
Free-Market Anarchism (or Market Anarchism)
Stateless society organized entirely through free-market mechanisms for law/defense/services. Common synonym for anarcho-capitalism (Rothbard, Friedman, etc.); emphasizes market process.
Link: https://en.wikipedia.org/wiki/Anarcho-capitalism (noted as alternate name)
Co-existentialism
Rules enabling peaceful co-existence amid scarcity/conflict via property rights. You suggested it (e.g., in Kyoto reflections) as a possible framing.
Link: https://stephankinsella.com/2009/06/the-new-libertarianism-anti-capitalist-and-socialist/
Notes on Hayek and Other Libertarians
Hayek did not propose terms for full anarchist libertarianism (he rejected anarchism, favoring limited government/classical liberalism and concepts like “spontaneous order,” “catallaxy,” and “several property”). Cato’s “market liberalism” draws on this tradition. Hoppe, Hazlitt, and you provide the main proposals above. The attached book reinforces Rothbard/Kinsella/Hoppe natural-rights anarchism without new rebranding.
You remain skeptical of rebranding as ineffective “branding” exercises; substance (private property, consent, conflict avoidance) matters more than labels. The book’s overarching framing—“Legal Foundations of a Free Society”—aligns with this focus on principled private law over any single ism.

In Kevin Carson’s Socialism: A Perfectly Good Word Rehabilitated, we are informed that the true libertarian is anti-capitalist and socialist. Well, at least Hoppe’s magisterial treatise A Theory of Socialism and Capitalism still has a suitable title–if you just switch the terms. (Incidentally, the image at right is a postcard I bought in 1990 in Berlin, right after the Wall fell. The post-Wall Germans were under the impression that socialism was a bad thing.)
But words have meanings. Socialism means centralized control of the means of production–or, in Hoppe’s more essentialist generalization where he defines socialism as “an institutionalized interference with or aggression against private property and private property claims”, A Theory of Socialism and Capitalism, p. 2; also see pp. 12–which is clearly incompatible with libertarian principles, by both standard- and left-libertarian lights. If we ignore semantics, even “communism” could work–after all, we are for community, no? But words have meanings and fighting over semantics is futile. Hell, we’ve even lost “liberal,” though there is some hope we can regain that (I recall Objectivist David Kelley once in a speech said, if the leftists are done with the term liberal, can they please give it back?). But “socialism”? Too late. If we were picking a new term, I might choose Hazlitt’s tentatively proffered term “Cooperatism” (Foundations of Morality, p. xii), but I think libertarianism, or anarcho-libertarianism, works just fine. It’s not the term that is the problem: it’s what it stands for. (As Rand said when asked: “Why do you use the word ‘selfishness’ to denote virtuous qualities of character, when that word antagonizes so many people to whom it does not mean the things that you mean?”” Her answer, as mine, was: “To those who ask it, my answer is: “For the reason that makes you afraid of it.””)
(As for “capitalism”–it is not at all incompatible with libertarianism, though it may not be the best descriptive or definitional term; but it basically describes a system in which the means of production are privately owned; this is indeed compatible with libertarianism, and an essential element of any libertarian society–and it is not “vulgar” to recognize this.)

Update: Hoppe: “I prefer the term ‘private law society.’” Hans-Hermann Hoppe, “Interview with The Daily Bell,” in The Great Fiction: Property, Economy, Society, and the Politics of Decline 2d ed. (Mises Institute, 2021), p. 505.
And see Kai H. Kayser, “APARACTONOMY AND ANARCHO CAPITALISM,” LIBERTY: THE MAGAZINE (Jan. 4, 2026):
Aparactonomy is a concept formulated and named by K. H. Kayser, derived from the Greek “aparaktos” (unbothered, undisturbed) and “autonomy,” representing a more practically oriented extension of anarcho-capitalism. It envisions a stateless nation guided by a voluntary constitution, with a strong emphasis on cultural cohesion, meritocratic diversity, and robust self-defense capabilities. Aparactonomy seeks to overcome some of the obstacles surrounding anarcho-capitalism, particularly its perceived vulnerability to external threats, to facilitate lasting societal and individual peace and prosperity (Kayser, 2025; Hoppe, 2001).

Every time someone tries to rename libertarianism or introduce another framing or vocabulary, it’s like they think it’s all just a matter of branding or persuasion, that you can trick people into thinking or saying they are really libertarian–e.g. voluntyarism, live-and-let-live-ism, nations of sanity-ism, panarchy, private law society, cooperatism, consensualism, agorism, autarky, polycentrism, market-liberalism, and now aparactonomy … it ain’t gonna work. People may be confused and inconsistent and quasi-statist but they are not stupid.
Update: I believe I read that Ayn Rand had mused that the term “existentialism” might have been appropriate to describe her philosophy, but it was already taken; and she found a way later to argue that Objectivism was a better term anyway. Since the socialists hijacked the liberalism, we started using libertarianism, even though it also refers to a philosophical view about free will. But others have proposed different terms, such as voluntarism, cooperatism, consensualism, and so on.
Walking around Kyoto, Japan, today, exploring Shinto shrines and Buddhist temples, I was reminded of the “Co-exist” decal and bumper sticker, and it occurred to me that another possible candidate for libertarianism would be “co-existentialism,” since the purpose of libertarianism is to provide for individual freedom and liberty in a world of possible conflict by establishing recognized property rights. To establish property rights so that we all might co-exist, to live among each other in a world of scarcity and possible conflict.
