>>12372164I've thought about that too.
Say you have someone with gender dysphoria. Now technically it's all their heads since it's literally a mismatch between their minds and bodies.
Ok, now say there is magical pill, that realigns their minds and bodies. Since it changes the mind relatively drastically, are they still the same person, is it not like eliminating their previous self in favour of something new.
Now, you still have continuity of mind, so my last point is definitely debatable.
At the end of the day, the important thing about a treatment is that people are willing to accept it.
Hell, if I put a bullet through someone's brain he'll no longer have any problems.
