Higher power~something spiritual? How about: blind faith that the non-aggression principle (not principal) is infallible and therefore all that's required to prevent chaos and disintegration of society when the government goes AWOL?
You are the only one claiming it will prevent chaos. There will still be chaos, as there is now under government rule, because there will always be assholes trying to commit crimes.
Sure, there is some empirical evidence suggesting that the NAP could work to diffuse or avoid a number of specific conflict scenarios. However, using inductive reasoning to conclude that "therefore it will work in every situation" requires a leap of faith. Myrkul's (and others') supreme confidence that the NAP will work, regardless of what situation anyone attempts to throw at them, shows faith in the NAP.
"Empirical evidence?" The NAP isn't going to do diffuse conflict scenarios, it will either prevent or eliminate them. To say otherwise is to claim that things like the threat of punishment or being actually killed by police will not prevent someone from committing crimes or stop them from being able to commit them in the future. The enforcement method is the same.
Besides, the NAP is a hypocritical statement. It "throws the first punch" by laying down the law and telling people what they can't do. I'd rather have a government because at least they consist of human beings who are capable of intelligent thoughts, unlike a dumb principle that any mindless drone can recite.
The opposite of NAP throwing that first punch is the government throwing the first punch by laying down the law and telling people that they MUST use aggression and violence against others. That's the opposite of NAP.
