Like I dont understand what you're saying at all because it seems like you want the social contract but also give anyone the agency to conduct violence and both cannot exists at the same time. We live in communities and created the police and law precisely because personal grudges and fights cannot scale and work to be a functional society. God i hope you are trolling
An example that requires police to be involved: Small Town A has a law stating that anyone dealing drugs must be caned for the first offense. Someone deals drugs in Small Town, so police catch them and cane them.
I swear, some of y'all just dream of being able to cane people or something.
