There is no coming back from a society that's become that fragmented and Purge-like for that long. No rules. No Constitution. No laws ( unless you're in an occupied zone or found a group that sets boundaries.)

Sure there is. Law is dictated by resource, both as incentive and enforcement. Unless nothing resource-wise can ever grow back because the fungus has ruined almost every potential crop, there will be a point where the risk of conflict over resources isn't worthwhile, since the resources are plentiful enough.

Or more simply put: if there is only enough food for one of us, we'll fight over it. But if there's enough food for both of us, why would we fight?
And which of you by worrying can add a single hour to your span of life?
