Many in the bitcoin world discover Rothbard and then believe they've stumbled upon a beautiful, self-consistent moral truth that, if followed, can fix most of what's wrong with the world. In reality, it's a silly utopian fantasy that is likely to come falling down quickly if you spend much time getting into the deeper issues of moral epistemology, brought up most notably by David Hume, which Rothbard quickly dispenses with in an almost neo-Aristotelean protest against the claims that all ethics must necessarily be subjective. Rothbard's contemporary, Hoppe, tries to put a lid on this contradiction with his "argumentation ethics" as well. But it's all resting on pretty messy metaphysics and epistemology.
