One of the problems with transition is that the transitioner still knows who and what they are, and they know that, for the most part, everyone else knows, too. For example, did anyone not notice the transwoman on Jeopardy yesterday, the one who was taller than everyone else in the studio and had obviously male shoulders, a male voice, and male facial bone structure? They know they're pretending. They know that everyone else knows they're pretending. It's corrosive to one's state of mind over the years.
