So wouldn't everybody just be better off going to court C in the first place? So court C would naturally emerge as a kind of universal dispenser of justice for everybody, automatically chosen by... guess what... society!
If everyone choose to go to court C that's fine because it's still voluntary. I'm against coercion, not organization.
So when the lynchmob comes for me I'll move on to another place and abuse more people. 'cos the lynchmob can't actually lynch me 'cos you're not allowed to be violent. Right?
I'm only allowed to use violence as a proportional response to you. If you steal my shirt, I can take it back. If you fight me, I can fight back.
