answer this for me - you need to be 18 to get a tattoo, fake t--s, drink (21 actually), vote, buy a gun etc. So why is it not unreasonable to have the same standards for gender affirming care, which is a highly novel/recent treatment?
Gender affirming care isn't novel or recent.
Gender affirming care does not necessarily mean surgery or medical transition.
Corrective surgery and other treatments absolutely can and does happen for people under 18 where there are specific reasons for it both medical, physical and psychological. You can debate the merits of it, but the idea it's not a 'thing' is disingenuous.
Not engaging with the points raised by the OP is poor form.
