Alan Greenspan parted with Ayn Rand's "invisible hand" objectivism at precisely this point. After outlining the objectivist idea that taxation was an evil, an act of theft by the government he said;
"Yet if taxation was wrong, how could you reliably finance the essential functions of government, including the protection of individuals' rights through police power? The Randian answer, that those who rationally saw the need for government would contribute voluntarily, was inadequate. People have free will; suppose they refused?"
Some people think Ayn Rand was immoral or amoral, she really wasn't. She had a kind of a "trickle down" theory of ethics. A person acting in his own best interest would end up naturally moral, an "invisible hand" like force at work in a community of like minded individuals. A pretty subjective idea in my book, one that may sound great philosophically but tends to get mired in Gekkoian self centered greed from what I've observed lo these many years.
