You're assuming the living space is itty bitty. Also, you're ignoring the whole "self defense" aspect. If the living space is sizable, and it's capable of defending its inhabitants, why is a government necessary?

The itty bitty was to this self sustaining contraption that vomits food and water in this hypothetical. Self defense? People have that now and it doesn't stop too much. Unless you want to go into the gun debate again. 

Look, from all I have read about history or philosophy, human beings need a leading body. Not just to give them the food or water they need, but to help maintain order. Wars over resources are not the only wars. Wars over land are not the only wars. Riots aren't just about food, water, or land. Yes those are huge components and if we had unlimited of all of them a lot of conflict would stop, but not all conflict. That's just unrealistic, from everything I have read or seen.
