All murders happen because of emotional (killing someone in anger), economical (Theft gone wrong) or psychological (Doesn’t realize it’s wrong) reasons. none of these is prevented by sticking the murderer in a box after the murder.

All of these are prevented by building strong social network to manage any harmful impulses before something happens, which is something any reasonable anarchist would agree with.

Also If you think the list is incomplete then feel free to give another example.

Oh yeah also political assassinations and wars. But your comment already addresses those.

I think a better wording is that anarchy is naive. And I’d rather be naive than accept that this is the best we can come up with, because that’s depressing.

There is an entity for keeping order. Its called a community. Everyone protects everyone because everyone knows everyone because everyone needs everyone. If you step out of line people won’t protect you.

Stateless societies existed for millennia before all the states came along and enslaved them. They had order because strong personal relationships maintain order without leaders.
