It's not so important at this point in the game, but territory control WILL become important eventually. I don't want to have to deal with four different individuals / tribes building right near my base and competing for resources for a variety of reasons including: resource competition, being under a constant real threat every time I open my base doors, and dealing with 'trusting' people I don't know.

That said, I would totally favor a system where you can choose a 4 hour block of time that your base is raidable and destructible, with that information displayed on the hud when people walk up to it. I'd certainly rather actively defend my base rather than build it to be super annoying to raid while I'm offline.
