Let's not forget what a diagnosis of gender dysphoria actually is.

Diagnosis of gender dysphoria involves children demonstrating at least six of a series of behavioural traits as well as an “associated significant distress or impairment in function, lasting at least six months”.
Those patterns of behaviour include:
• A strong desire to be of the other gender or an insistence that one is the other gender.
• A strong preference for wearing clothes typical of the other gender.
• A strong preference for cross-gender roles in make-believe play or fantasy play.
• A strong preference for toys, games or activities stereotypically used or engaged in by the other gender.
• A strong preference for playmates of the other gender.
• A strong rejection of toys, games and activities typical of one’s assigned gender.
• A strong dislike of one’s sexual anatomy.
• A strong desire for the physical sex characteristics that match one’s experienced gender.

These are the things they wish to "cure" by drastic surgery. Wearing clothes and playing with toys that others have said are wrong, and not liking your body.
Also, let's try not to conflate "being trans" with "has gender dysphoria". Many of the T community have rejected this as it medicalises their identities, and many trans people realise that physical sex and gender are different.
