Sure, everyone has their own right to live, but no one's right to live takes precedence over any other person's right to their own body; that's why organ and blood donations are optional and not enforced by the state, because even if a person will die/is dying, you still have the right to deny them access to your own body. Your right over who can or cannot use your body, at any time, for any or no reason, is absolutely more important than any other person's right to life; simply having the right to live does not entitle someone to another person's body, even if their life literally depends on it.
