I can't have a thoughtful, deliberative position WRT total nonsense. What ontological sense does it make to say I "own" my body? Or that I "own" my mind, or my soul? Or my nose, my ears, my hands, etc., etc.? A human being is an organic, dynamic composite of all these necessary things. These are not things we "have," in the sense that I have a house, or a car, or a career, or a cat; these are things that make us what we are, things that pertain to our essential being. What sense does it make to say that we "own" what we, in fact, ARE? The question is idiotic, because it presupposes a total abstraction and reduction of what a human life is, and then sets up "relations" between the self and the body that do not exist in nature.
Actually, the topic is so deep that to dismiss it in a few sentences doesn't give it justice. Thinkers and seekers of the truth, as well as spiritual practitioners from all religions, have concluded that the self is the eternal soul/atma, and the body is a temporary vehicle or covering that is in our possession, for a time.
