As someone who is personally a minarchist, I'm wondering how the Non-Aggression Principle would be enforced in the AnCap model.

Given that there definitely is definitely no executive branch, people would obviously have to take personal defence into their own hands. But would there be trials for people who pollute your land? Surely not all 'aggression' is the type that would give you the right to shoot someone on the spot?

On another note, what about defense from external forces? You would need an organised and unified military. While I hate the government, I cannot understand the AnCap solution to an armed conflict with another country .
