I agree with your views on 2 & 3 but not #1.

Believing your body is someone elses responsibility or controlled by someone else removes the self of self-responsibility for it. Knowing it is yours and up to you to determine what to do with it brings this fact into obvious recognition.

I realize your post regards responsibility in general and not simply self-responsibility, but responsibility for someone elses body is a priveledge that is granted by the owner of that body, not a right inherent to someone else. We need to be careful to respect the freedom others have, especially with regard to something as intimate to them as their own body/person. It's very likely when someone attempts to assume responsibility over someone elses body the "owner" feels less obligated to assume the responsibility themself.
