This is a good critique of the more extreme forms of libertarianism. I think a lot of the reason libertarians go wrong is they have a mistaken view of human nature that ties in turn to a mistaken view of the original state of the human human race. The seem to believe humans originally lived apart from each other, and so have the psychology needed for that sort of existence, and only later joined into societies. But actually, the scientists have determined that humans originally lived in small foraging bands, and so have both individual and social instincts, such that a libertarian society simply would not work. A good book on this is Darwinian Politics: The Evolutionary Origin of Freedom, by Paul H. Rubin.
