Of course it does. I included quantum physics, as to the best of our (collective! see?) knowledge, it adequately describes (some aspects of) reality. The fact that the same initial conditions need not always lead to the same outcome is, IMHO, tangential to the question of free will.
Do you have a better explanation for the wide variation of human behaviour? Tangential? I don't think so. As you pointed out, we are governed by the same physical processes that govern the rest of the universe.
I think you need to question your basic assumptions a bit closer. No offence meant.
I know that I know nothing. ;-)
I know nothing but what I observe...
But is territory really comparable to property? AFAIK animals only claim (and defend) the territory they need to survive, either alone or in a group. They don't (again AFAIK) have the tendency to claim ever bigger territories and use social constructs to defend them.
If what you said was true, then animals would not expand into new territories that would force them to evolve; which is obviously false.
BTW, humans are just animals - evolved ones, perhaps, but still just animals. There is little that differentiates us from the rest of the life on this planet other than our technology.
