I don't understand this. The core problem with gender dysphoria is that you feel significant discomfort with your biological sex. If it were possible to legitimately "re-educate" oneself to not feel this discomfort, that would be considerably cheaper, less invasive and less problematic overall than trying to change one's sex. All surgery carries risk of death after all, and lifetime of hormone therapy is annoying to say the least.
Being bald is not just a feeling of discomfort with having no hair, it has real consequences. Baldness is generally considered to be less attractive, and attractiveness impacts career and dating prospects, for instance.
Being impotent also has real-world consequences. It impacts dating and also impacts your ability to conceive.
Arguably, being trans also has real-world consequences as well, so if a solution became available that could eliminate the gender dysphoria without changing your sex, I would be very surprised if plenty of trans people wouldn't choose that option, and not just because of social stigma.
The resistance to such a solution comes from two understandable directions: a) terrible gay conversion therapy that doesn't actually work, and b) the (mistaken) notion of mind-body dualism that many people internalize over their lives, that their identity, their mind, is separate from their body and has more primacy.
