I think in order to sole the issue things like ba, ffs, etc could be required. If srs is a treatment for gid then surely all one needs is insulin if they are diabetic. The truth is there is more to it than that. And while cost mqy be higher giving more comprehensive care, the amount of transpeople seeking surgery isn't likely to make much impact. And if it really mattered then there wouldn't be McDonald's in the UK, as i am sure that is more of a drain on nhs than transpeople ever could be.
I would also like to note that here in america, even just getting the srs seems like a dream come true and it is out of reach for many of us, but it is only right that we have solidarity with those fortunate enough to have been born into countries with national health care too, her struggles are not made any less valid by our own. If that were so, then we have nothing to complain about versus a great many third world transpeople who have clean water, much less hormones out of reach.
