It is not true for libertarianism simply because it is far too enamoured with the Smithian ideal of the self-interested rational actor. While this has been a useful model in economics, it is not an actual description of the world, which economics has had to come to terms with as a field. That's why libertarian ideals only makes sense in fantasy land and don't map onto the world. Most people are not acting only in self interest.
