So are you saying we should do away with legal gender only to have de-facto legal gender used for all sorts of things like sports or insurance policies? Who's going to standardize those determinations if it's not the government? If the government's standards aren't good, and are in fact simply "genitals at birth", then that needs to be fixed, but as far as I can tell that's not true, at least federally or for the state I checked. If you transition, you get a court document with a doctor's statement certifying it, and you update your gender on your official documents. Right? There probably need to be different legal standards based on the purpose the gender is being used for, too. Being a trans woman shouldn't allow you to compete in women's MMA, for instance; there's already been an instance of that happening and it was a disaster. What concrete problem or injustice are you trying to correct? That people can't decide to change genders for a day, or decide they want to be officially recognized as the opposite gender before they transition? Is that a problem? People seem to want [biological] sex labels to mirror how they present themselves to others, instead of mirroring (as closely as possible, based on the reason the gender label is being requested) the underlying sex characteristic / hormonal physical reality of their body. That strikes me as a problem. In the limited situations and cases where people are asking for [biological] gender and need to know, how you present yourself ceases to matter. If they don't need to know, they you can use whatever label you want. Same with your name, or your date of birth, or anything else. But it's almost always pointless to informally declare your gender, because anyone interacting with you is going to pick up on what gender you present yourself as (whether verbally, in temperament, or physically). Labelling yourself other than your biological gender isn't needed for enlightened, tolerant people, and will only antagonize people who aren't comfortable with the whole trans/non-binary thing.
