-The coordination problem of _who_ has the authority to decide what "gender" a person is, can be seen of a particular case of the problem of how to decide what gender a person is _in a particular context_. The notion of the same person's "gender" being differnt in different contexts may seem strange, but again, in the absence of magical perfect sex-change technology, we _kind of_ need it: as far as the practice of medicine is concerned, there's no getting around the fact that pregnant trans men are female. (Even if the doctors _address_ the patient as "Mr.", "he", _&c._ they still need to draw on their knowledge of the _female_ reproductive system to practice their craft, and they might need _language_ that reflects what they're actually thinking.)
