I have thought about this question too sometimes, but instead of considering it in an abstract manner, I would first ask - how exactly is 'curing' dysphoria possible without transitioning?
If it is true that our gender identity is decided in the brain, and if it is the brain where dysphoria occurs because of a mismatch with our bodies, then the only way it can be cured without a physical transition is by doing something to our brains. It is not possible currently but may become possible some day, so it may not remain a hypothetical question. But this is where I have to agree with those who say that if their dysphoria were to be 'cured' without transitioning, they would no longer be themselves. Somehow I think doing anything to our brains to 'cure' or 'change' one thing will have an effect on how the brain works in other ways too, which in turn will affect who we are as people.
So what would I choose - changing my brain which decides who I am, what I feel, how I think, how I decide, what I want, what I care for, and who/what I love?
Or changing my body which only does what the brain tells it to do, and which we anyway keep changing cosmetically all the time?
I would keep my brain as it is, be who I am, and change my body. In other words, I would still want to be female.
P.S. Looking at it another way, I think HRT does change people's brains, in the right way. I would want that kind of change, but I think that's not what the original question was referring to.
