We allow people to self-identify their religious beliefs. The government doesn't declare you to be a Catholic or a Buddhist and force your driver's license to say such.

Unless you're proposing making the military- and the rest of society- radically gender neutral, than as soon as a person interacts with a driver's license, passport, social media account, or bathroom, they will have to adopt a gender identity . Why should a third party's "gender beliefs" about a person be elevated above their own?

(I also can't see a justification for denying hormone replacement therapy treatment- it's cheap and ridiculously beneficial for mental health. But, for the same reasons, I advocate its availability over-the-counter.)

The architectural solution to gender neutral bathrooms is floor to ceiling panels and doors that actually close. It's quite simple and extremely common in newer buildings in Europe.

Driver's license and passport record sex, and bathrooms and other spaces that are separated for women and men are done so on the basis of sex.

Being an objective measurement of material biological state, sex isn't the same type of thing as a gender identity belief, which is indeed self-declared like a religion is.
