XKCD said it best: "I had a hard time with Ayn Rand because I found myself enthusiastically agreeing with the first 90% of every sentence, but getting lost at 'therefore, be a huge asshole to everyone.'"
But yeah, it's a gateway drug to the full goldbug, especially because it plays on a teenager's native arrogance to convince them that they're following a philosophy of selfishness for the elite. (I was immunized, ironically enough, by being in my nihilistic phase when I discovered Rand. If you don't take it on faith that you shouldn't hurt other people because you feel like it, Objectivism isn't for you. )
Interestingly, Leonard Peikoff (head of the Ayn Rand Institute) argues for a sort of accelerationism where every Objectivist goes on welfare so that the dead weight will drag down the system.
Obviously, he's wrong, but I actually find this to be a valid move simply because it's a scientific test of Atlas Shrugged's theme (and it's in keeping with Objectivism because the existence of welfare systems is an initiation of force, through tortured Objectivist logic). "If we tell society to fuck off, can it go on without us?" If the answer is "yes," then we can just let them drop out. "Who is John Galt? Who cares?"
