I'm struck by the irony how they define ownership: I belong to something else - not something else belongs to me ;)
It's not just a cultural / societal thing either - I actually belong to the state and in part society by law: I'm not entitled to make decisions about my life per se and I'm forced to donate a (greater or lesser) part of my life to the country / society I live in. Thus I'm the property of this state / society / family who dispose of my life and and my actions as they see fit.
Do you happen to know a country, society, family, even a hermit, no matter how remote or far in the past, where an individual belonged only to itself and did not have to fear repercussions from others? Repercussions usually of the violent sort, as that seems to be the universal mode of enforcing ownership ;)
If I do not have that basic ownership over myself, then everything else is just a matter of degree of ownership by others ... or how much force I can muster to keep them off :P
