There are a number of plausible Libertarian solutions to everyday political problems. The initial allocation of natural resources, or dealing with crime, are rather well covered. However, all of those solutions are based on the availability of some kind of legal system.

There are a fair amount of decently argued Libertarian *justifications* for new kinds of legal systems. I have, however, been unable to find a response to those who like to kill the justifiers of legal systems before they can finish their argument. Warlords, despots, conquerors, and their potentially numerous, skilled and well-organized henchmen.

Convential wisdom has it you need an army. But if you have an army, are you not a state in all but name? And if you don't have an army, who protects citizen's rights from the non-enlightened barbarians who do?
