Fixing brain problems is hard enough when we do have an idea what we're doing, and if the transitioning/fix doesn't work out, fixing my body from their drugs seems way easier than fixing whatever the drugs might do to my mind.

Probably better to not take any drugs whatsoever, and definitely better to not get any surgeries. If you think that detransitioning your body is somehow "easier" than fixing your mind, you should listen to some detrans stories.
