That sounds pretty reasonable. I wonder if Boudicca agrees that official government ID should be a part of any self-ID regulation.
Do you happen to have the Canadian regulations handy? Does Canada require that you have the government ID in your possession? Or do they require that self-ID be honored even if the claimant does not or cannot produce the ID?
One concern I have about government ID is the same as my concern about medical transition as a requirement. When we talk about voter ID, there is HUGE push-back on the grounds that not everybody can easily get one. Voter ID is held to be regressive, effectively a poll tax, and essentially bigoted in nature.
So it seems to me that requiring government ID would be similarly problematic. It doesn't seem fair to tell Boudicca and others, "you can't fully live your identity until the government signs off on some paperwork".
Now, if trans rights advocates were to take that position, "it's not quite fair, but it's a good solution and it's the one we support", I'd be willing to accept it as well. But is that a TRA position?
You've said that Canada has this policy. You haven't said if you agree with it, or why you think it's a good policy.
