There will be rules based on location no matter what you do. You don't need a state for that. People live in places, and they have customs and etiquette and rules of decorum. You probably won't be able to walk around naked in Kabul no matter whether there's a state or not.

the state is needed to protect this person from undue punishment and give them a fair trial. the same goes for benign things like traffic violations or for murder. the moment where a rule violation crosses multiple groups you get an issue with jurisdiction. the only way to resolve that is by having an entity governing rules for the locality. otherwise justice can't be enforced.

now again, we don't need the nation states from today to do that. a global system would be better, but we still need local enforcement and local influence over what the rules are. there is simply no way around that if we want to protect all individuals in a location.

in general when it comes to enforcement of rules and punishment, the only groups that will survive will be faith based ones, because for any other group people will simply leave if they feel they are not being treated fairly. we can already see that with the controversies around some code of conduct violations. only the people who have a big stake in the group or depend on the group will accept any punishment. others will just give up and find another group.

the only way to avoid that is to have justice be handled by an independent institution. it can't come from the group itself, or we make it difficult to switch groups.
