A possibly obvious point. Libertarianism is a doctrine about the limits of state power. It is not a doctrine about individual excellence or individual morality. In particular, libertarianism does not hold that self-regarding behavior (behavior that doesn’t harm others) is morally permissible. It just says that the state cannot criminalize it. For example, I may insist that the state should not criminalize prostitution while believing prostitution immoral. (Same with aestethic values: I think I have reasons to support the claim that the music of Mozart is objectively better than the music of Lady Gaga, yet I would join Lady Gaga’s fans in opposing the state’s attempt to impose Mozart.)
Yet, as Jacob’s post suggests, libertarians share with progressives core beliefs that go beyond limiting the role of the state. Yet, are really libertarians and progressives essentially in agreement about virtually everything, except the role of the state? I am not so sure.
