In a real situation where people are fending for themselves, the only way to determine whose property something is by force.

I like the rings of preparation idea by the way. Great method to keep focused. I've camped all of two times in my life and generally have no idea what I'm doing so I grossly over pack and bring all kinds of random shit that I never end up needing. Like I'll bring shoelaces or something, with no real purpose in mind, just "in case." Having a plan, to make your plan, helps keep things simple and prevents you from pushing around a shopping cart full of the contents of your junk drawer.
