Libertarianism

Libertarianism is basically about negative rights - not so much about "do what you want", but more about "nobody is going to force you to do something you don't want".
As an ethical system, think of it as utilitarianism which assigns infinite value to freedom from violent coercion. Everything else follows from that.
