There's your fixation on property ownership again. The world is more complex than your simplistic paradigm allows for.
Your posts are becoming less about debate and more about abuse. If this is all you have to offer, you will be ignored.
Property ownership is the key to determining what is aggression. If you take the shirt I'm wearing, are you the aggressor? Well, it depends, if it's my shirt, yes. If I stole the shirt from you yesterday, you're just reclaiming your property. We can't even determine which acts are acts of aggression without a theory of property rights.
And your theory is overly simplistic. Study ecology.
