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 is your opinion, but consider another topic: elective disablement. Some people are very insistent on having their spinal cord surgically severed or getting their arms and legs chopped off or being permanently blinded, or similar.

If you naively consider the topic only from a bodily autonomy perspective, then the answer is deceptively simple: get the blades out and start slicing. But this ignores the wider medical ethics concerns over whether it's the right thing to do for the patient, if the surgeon is causing harm by doing so, if gratifying the patient's short-term desires genuinely helps them in the long-term over their entire life, if it's reasonable to expect a surgeon to perform such a procedure and how they may feel in the aftermath, if there are any other interventions that would be more effective. And societal questions over whether it's ethical to deliberately add new members to a population who already find it difficult to find the support they need, how this will affect others who may now be situational obliged to assist with this person's new disability, and so on.

It makes no sense to focus solely on the individual and ignore the wider context, when there are so many other factors to consider.

That's a narrowly individualistic view of the role of medicine in society.

Medicine has a social context as well. This relatively recent idea that someone can become more female or more male through drugs and surgery is one that has repercussions on how we as a society view the two sexes, what constitutes a woman or a man, and what is an acceptable expression of one's masculinity or femininity.

Maybe it's the right idea. But we should all reserve the right to be critical and consider alternatives, for this and any other idea with broad societal implications.
