Those needs are from the most basic to the highest:
Body Needs {I'm hungry/I need to heal}
Security Needs {I don't like to be hit}
Social Needs {Doing a piece of a larger whole and/or RP}
Ego Needs {I have a role in this location that is needed}
{and there's more but let's stop there}
The more resting and food gathering becomes difficult the more reliance there would be on a goverment or some kind of agreement to work it out.
I was thinking the reason why these things are easy is so that goverments can concentrate at the Security level whihc I think is the IRL norm. If we make everday life harder then the "goverment" or just people in genreal will have to start working together more.
Is that more goverment or just more cooperation. It may not influcence the development of goverments at all by making things harder.
I think the only thing to strengthen the goverments is more organized threats to indiviudal secrity in game. And I'm working on that.
I still like the idea of walled towns.
Just something to think about.
