Not to be accused of condescension by pointing out the obvious, but there's nothing in that opinion piece connecting the thing that we all agree is bad (the fact that medicine for thousands of years has largely privileged male perspectives and male bodies) with the thing that the author is most keen to complain about (their strawman version of trans-inclusive language). I was gearing up for a bit of debunking, but unfortunately there's nothing I can get my teeth into :( It does just feel a bit like the author wanted to talk about a few disparate trans-related things that happened in the last week or two and was struggling for a through-line.
I agree with @Flickersy that there's a potentially interesting article/study with regard to how inclusive language helps/hinders access to public healthcare services, but this ain't it.
