That said, there does seem to be something that smacks of hypocrisy in the case of the Ayn Rand case, more than in the Warren Buffet case. I think in particular, it's the idea that society would somehow be better without such safety nets: If you're using the safety nets, that's kind of proof that they're a good thing, isn't it?
In your hypothetical scenario, North Koreans would certainly be able to sort themselves out without the daily handouts if they weren't being oppressed by the NK government.
Is it the case that the Ayn Rand Institute would have been perfectly capable of supporting themselves in this crisis if everyone had just been paying lower taxes and had fewer regulations? Perhaps people at the Institute think so, but I'm pretty skeptical.
