Rothbard’s Objectivist Influences

by Stephan Kinsella on November 4, 2025

Mises and Rand (and Rothbard)

Objectivists have long been bitter that libertarians accept most of Objectivism’s politics without accepting the rest of her philosophy: mainly, its metaphysics (objective reality), epistemology (reason), and ethics (self-interest), although most individualist-leaning libertarians more or less do happen to accept these three broad views. Objectivists somewhat crankishly refer to their politics as “capitalism,” just as some anarchist libertarians sometimes use the term anarcho-capitalism. ¹ Objectivism’s capitalism is virtually the same as minarchist libertarianism, ² a term Rand petulantly rejected, even though Objectivism’s “capitalism” is virtually the same as libertarian minarchism; in fact she is one of the main figures behind the modern libertarian movement. ³

Objectivists seem to want libertarians to be Objectivists, but only if they adopt the entirety of the rest of the philosophy. And because of their insane, nearly-Galombosian-level crazy IP views, ⁴ they are upset when anyone uses what they think of as Rand’s ideas without proper attribution and obeisance.

This is true also for Rothbard, who for a time was involved in Ayn Rand circles, but his refusal to go along with their cultish ways led to an inevitable split and to Rothbard’s mockery and criticism of the “Ayn Rand cult.” ⁵

In any case, Objectivists have been bitter at Rothbard ever since for “taking” Rand’s ideas and not giving proper attribution to Rand—even though attribution would also not satisfy them, since he rejects too much of their philosophy (e.g., he’s an anarcho-capitalist instead of Randian minarchist). ⁶ For example, Daniel J. Flynn, “Murray Rothbard’s Lost Letters on Ayn Rand,” notes:

“Murray Rothbard never cites Ayn Rand once in any of his works in which he defends Aristotle, in which he defends natural rights, or free will—ideas he clearly got from Ayn Rand without giving her a single citation,” Objectivist writer James Valliant claimed on a 2021 podcast. His interlocutor, Jonathan Hoenig, a Fox News Channel talking head, speculated that Rothbard “largely fictionalized” his accusations against Rand. “It’s a load of bullshit, basically, just designed to denigrate Ayn Rand because he was called out plagiarizing her,” he said to Valliant. “Am I summing it up?” Valliant maintained during the podcast that Rothbard “got Aristotle and natural rights straight from Ayn Rand.” ⁷

In response to charges that he “plagiarized” Rand without giving her proper attribution for ideas he “got” from her—again, even though this would not mollify our IP-crazed cultish Objectivists—Rothbard responded by citing earlier progenitors of the ideas Rand claimed to have pioneered, which only angered them further. (See also Rothbard’s Lost Letters on Ayn Rand, a discussion between Ryan McMaken and Daniel Flynn. From a friend: “they purport to refute the claim that Rothbard took ideas from Rand by citing recently discovered letters he wrote to Frank Meyer. But they seem more narrowly focused on the claim that he got natural law and Aristotelianism from her and don’t address these other points.”

)

I have always been bemused by this tactic of Rothbard’s. I understand why Rothbard was reluctant to footnote or give credit to jerks who had been so unfair to him and his wife; yet I would not have done it. I have given credit for example to the late George Smith even after we had had a nasty personal/legal squabble. ⁸ I do not think Rothbard did anything wrong and in fact find it kind of amusing that he bent over backwards to cite older variants of ideas Rand later propounded, or simply refused to cite her works where relevant to the point he is making. I have seen this in lots of libertarian books by non-professional scholars, ⁹ but it is somewhat surprising to see this in a truly towering figure like Rothbard. ¹⁰

In any case, I have myself read a large amount of Objectivist literature and also Rothbard, and I noticed many times an argument or point made by Rothbard that seemed like one he probably got from the Randians. I didn’t start cataloguing them but have created this post to do so when they occur to me from time to time. Just to start, more later:

Free will: Rothbard’s argument is similar to that of Rand’s (and similar flawed IMO; more on this later)

Apriori reasoning/axiomatics: Mises and Rand (and Rothbard): apriori reasoning like Rand’s

Referring to the Non-Aggression Principle as the non-aggression axiom

On defending the rights of Americans in socialist countries: Rand somewhere argued that if you go to the USSR, you take your chances and the US has no obligation to defend you. Rothbard argued similarly. See Block on Israel, Self-Defense, Pacifism: Rothbard writes, in War, Peace, and the State: “if an inhabitant of country A should move to or invest in country B, the libertarian must argue that he thereby takes his chances with the State-monopolist of country B, and it would be immoral and criminal for State A to tax people in country A and kill numerous innocents in country B in order to defend the property of the traveler or investor.8“

My comment there: “This is yet another example of one of Rothbard’s views influenced by Ayn Rand, where he does not cite or give Rand credit. She said, IIRC, in response to some question perhaps, that if an American citizen travels to a despotic regime which then jails or harms him, the US government has no obligation to intervene because the citizen assumed the risk by traveling to such a regime”

I have for many years tried to avoid the term anarcho-capitalism, since capitalism is just one aspect of the economic system of a free society, and not necessarily the only one. I tend to prefer the term anarcho-libertarian, anarchist libertarian, or libertarian anarchy.

His criticisms of Nozick’s arguments for minarchism apply more less to Objectivist arguments for the state. See Rothbard, “Robert Nozick and the Immaculate Conception of the State,” in Ethics of Liberty; David Kelley on the Necessity of Government. [↩]

See Tom Woods, “Interview with Hans Hoppe,” Tom Woods Elite Letter Issue #18 (Summer 2025): “And there was a certain amount of, I would say, jealousy, because, I mean, Rothbard was enormously bright. I’ve met bright people in my life, but the only person I’ve met whom I would consider to be a genius was Rothbard. He could tell you the the content of every book in his library. And that was an enormous library. Whenever you would ask him about any strange subject, he could give you some suggestions on what to read. You felt like a little, um, uneducated person if you talked to him. So jealousy played a big role in explaining why it was that he was not treated like a genius, as he should have been treated.” And Tom Woods, “The Hans Hoppe Interview Concluded,” Tom Woods Elite Letter Issue #19 (August 2025): “There are certain purely theoretical points, like the foundation of private property rights and so forth, where I think I did make some breakthroughs, which Murray endorsed. I’m very proud of that. But since I’m now 75, if I had to assess my general impact that I had on the world, I think it would make me most proud if people would say Hoppe is, in a way, the most important successor of Rothbard in the present age. It would make me enormously proud if that became the general view, even though I admit I’m not in the same league as Mises and Rothbard. Those two were geniuses. I’m a pretty bright guy. I contributed quite a bit to libertarian thought. But I would never, ever put myself in the same league as them. But since there is nobody in sight who is in the same league as they are for the time being, I’m a pretty good substitute for these two giants.” [↩]
