I get what you're saying but maybe i need to think of the other sides. If a boy takes puberty blockers and then goes on cross-sex hormones 2 feminise himself, that will change the basics of being a man. It's not going to make his organs smaller including his lungs, it's not going to make his arms shorter, it's not going to make his legs shorter, and it's not going to widen his pelvis and reattach his femurs to make it enough like an actual female but with science we might develop that. The boys I've seen who took puberty blockers and are now trans women still have some masculine features, but they have tits and they didn't really get the heavy brow of men which is pretty much it but it's a step forward.
