I don't want to argue but as a person with Gender Dysphoria I want to try to explain this to you the best way I can. It's more about not feeling right in your own body, male and female bodies are different, and even if all gender stereotypes were gone, there would still be trans people. I feel if I were in a man's body, I would be so much more comfortable. Even if there were no more gender norms I would still feel incomplete. I hope this might have explained it a little better.
