The problem is people have proven time and time again that given choice #2, they'll take #1 instead. Market forces do not keep greed in check.Unfettered self-interest is evil...or it leads to evil. "Do what thou wilt shall be the whole of the law," is not libertarianism, at least not according to what I posted in the OP. Closer to the mark is, "if it harm none, do what thou wilt."
Big difference. I think an entire society could be based off of that principle alone.
