Reply #23: You're right, I cannot think of a libertarian nation

although your idea of the pre-Constitutional American colonies-turned-states being an example of a non-viable entity is not without flaws. If we had not created the Constitution, if we had functioned effectively as thirteen (or more) independent states trading with each other due to simple proximity and common European ancestry, perhaps we would have flourished.

We'll just never know. In any case, it never happened, and that's what makes your final sentence quite true.
