I mean theoretically cishet people would be able to take advantage of all the measures I have proposed. Definitionally thought, cis people wouldn't want to legally change their gender.
Hmmm, that's still a privilege and not a right. Not that I object in principle to the underlying goal, just to the framing.
I don't know if you're too young, but during the gay marriage debate pushback was "we already have the same freedoms! I am allowed to marry people of the opposite gender and so are gay people!". It was BS, and we have to look at the legal solutions that worked. Every region that said "gay people are allowed to marry people of their gender" created unsustainable Common Law privileges. Most sensible regions just created a more sweeping right "you're allowed to marry anyone, regardless of gender". Not a privilege, but a right.
The way to get properly funded treatments that created rights, but not privileges, is to create universal healthcare akin to the UK's framing. In healthcare, we use something called
DALYs, which essentially measure the efficacy of a treatment based on how much it improves the quality of life of the recipient. It's not just adding pure lifespan, because everyone know that extended years of suffering aren't the same as extended years of health. The UK buys DALYs for its people based on an efficiency ratio, which (having in worked in the field) I rather like on a theoretical level but with the caveat that it was the first economic theory on delivering sustainable healthcare I was truly immersed in, so I'm hella biased.
So, if you frame it as a
right to healthcare based on need, then it universally works A cishet person never will need that specific therapy (unless it's to access some insane privilege in a progressive location that doesn't write sustainable laws wisely), but it doesn't matter, because the creation of that net catches them in whatever way back luck gets them.
The science of medical intervention to assist transpeople is still in its total infancy. We have a variety of opinions on what
may help and what people
feel helps, but we have no long-term data. Assigning the DALY model means that we get ratcheting improvements overtime. Any intervention we fund runs the risk of being suboptimal, so if we fund specific interventions instead of the model we create a bad system where bad treatments get locked in. The American health R&D system is pretty terrible, and full of perverse incentives, and you don't want to stack more bad policy onto old bad policy.
