One of the problems that plagues both Neo-Reaction and Libertinism(Rothbardian Cosmopolitan libertarianism), is the lack of formal logic (building proofs: criticisms) means both disciplines attract lunatics. And there isn’t any defense against it.
I had always considered Propertarianism’s rather challenging learning curve as a negative. But in light of what I’ve seen, it’s actually a positive. Either you can construct a Propertarian argument or you can’t. If you can’t, well, then you don’t have anything to say.
