I have seen a recent interview (last few years) with him where he still refers to himself as a libertarian, but I agree that in practice he does not seem that way. He is heavily influenced by Leo Strauss[0] however, so he may be taking an "esoteric" view of what libertarianism means. [0]: Strauss was a political philosopher who advocated reading the "esoteric" meaning in works of literature. I.e. he thought that thinkers did not write what the actually thought but wrote in a veiled way so that their true meaning was apparent by those in the know, but not to casual readers.
