Why wouldn’t some trans people physically transition?

Help me out here cause if a trans person had the means, legality and money to physically transition why wouldn’t some?

Isn’t the point of transition in the first place to have your body better reflect your gender identity? Hence why trans people get hormone replacement and surgeries to be more comfortable in their bodies? Is it a societal problem? Personal fears? Surgical fears, medical issues etc?

I don’t mean any ill will or anything so please forgive my ignorance on the subject.
