"I claim this piece of land for my own. Oh, look! There are people living on it already. I guess I get to enslave, rape, torture them."<p>Actually, you can say EXACTLY that. The very idea of private property is founded on that principle. When whoever it was originally decided some plot of land belonged to him, that's precisely what he said. All I would add to that statement is the clause, "Or they can get the hell out."
