Starting around 1:30:00, another deeply flawed attempt to argue for intellectual property. It’s made all the worse in that it comes from an anarchist libertarian, J.C. Lester, author of Escape from Leviathan: Liberty, Welfare and Anarchy Reconciled (conspicuously not online yet. Why some people take time to write books but don’t want to make their ideas accessible is a perennial mystery—but in tune with the IP idea, I suppose). His entire Popperian “conjecturalist” approach is in my view flawed, as his is view that libertarianism is about reducing “impositions,” instead of aggression. See my discussion of some of this in “Aggression” versus “Harm” in Libertarianism.
Discussion of IP actually begins at 1:24:30.
