You consider genetical sameness, what about the epigenetic traits, aquired traits like sickness etc? It will be erased in a new organ, and it will make the brain function and percieve differently, which you may or may not be able to attribute to this particular transplantation, of course. But scientifically, we don't treat brain as some solid finite substance that exists (born? created?) in a fixed state forever, and thus can be moved here and there and stay same in it's uniqueness. Brain/mind main property is that it's dynamic, and this dynamism is brought through by the rest of the body, and the environment it lives in and senses and adapts to.

No different than getting some drug that improves your organ's health without replacing them. Perhaps via gene therapy, stem cell manipulation or whatever.

It does that whether you transplant organs or not. Your tomorrow's self will not be quite identical to today's self either way. Replacing body parts only changes the trajectory in a similar way a change of environment would. Perhaps a drastic change, but still a decision that people could consciously make.
You are right about the first, but then if these things could be captured and reconstructed at scale (not like now), there is no such thing as "conscious decision" anymore, at least for some. Because if someone is able to capture this molecular turn-over, which is a static snapshot of our interaction with the reality basically - then it's possible to manufacture and control it? Not like we are not controlled now, but this is like a kernel level of control, out of which we can't exist. Sounds problematic?
