To me, a right is something intrinsic to the self. A good example is the right to remain silent. Of course it is your right because, realistically speaking, I can't make you not be silent. Same for bearing arms so long as we are flexible with the definition of being armed. So, while it may be illegal the law simply infringes upon the right as opposed to removing it. If it can be removed then it is a privilege instead.
So it is with one's body. Abortion can be illegal or not but they will still happen. Vaccinations can be mandated but they will still be evaded. Thus, I refute your idea that rights are an antiquated notion. It is simply a new ideology to deny the fact that rights do exist. Otherwise, I thank you for your rather long winded exposition that boils down to saying that no, you do not want people to have the right to their own bodies.
