Well here's the thing, this has already been a hotly debated topic by medical ethicists and philosophers, who have indeed considered many factors other than the individualistic bodily autonomy viewpoint.
That's a mis-representation of what bodily autonomy stands for in the context of elective surgery. The ethics of medicine are a complex and very well established domain that extremely cautiously moves forward to ensure they get it right. And when they do not the damage is incalculable, for instance gay conversion therapy and other such niceties.
So before you go off on a tangent about what is and is not accepted practice and which things doctors are required to do and which things they abstain from on ethical grounds I will have to bow out because we are at the limits of my knowledge on the subject and that's not for want of reading material. Let me close with: I know where the line lies in simple cases, but if you start dragging in things that I have not spent enough time on/read about/have knowledge about then I simply will not be able to hold that conversation. If you have this knowledge then more power to you, but so far you have not convinced me of it and you come across as an ideologue.
So this strawman won't stand.
