Ron Paul's position echos Rothbardian one - natural individual liberty is an axiom (given by god or nature.) Herman Hoppe proved later that Ayn Rand was correct. Rothbard agreed with Hopper, but both of them never mentioned Ayn Rand and the fact she was correct.
The hate of Ayn Rand comes from plotical religious "right" and progressive left alike, because Ayn Rand was the first to show that religious and socialists share the same morality of sacrificing an individal man to an abstract entity (universal neighbor or society.) Since an abstract entity cannot collect sacrifices, wise central planners and special interest groups step in to collect instead.
