In all seriousness, drawing out again another ADHD analogy. I think you and a few others (including maybe sockma) pointed out that ADHD is overdiagnosed (it sort of is and it isn't....if it's a spectrum like autism it actually means its wildly underdiagnosed since a huge portion of the population is probably somewhere on the spectrum but what may be getting overdiagnosed is the need for medication). One problem with the overdiagnosis is that until recently, there wasn't really a scientific way to screen who is ADHD. The doctor (many times a pediatrician not schooled specifically in ADHD, or a psychiatrist whose one tool is a hammer and so everywhere he sees a nail and goes ahead and writes script) basically relies on a survey of questions to parents, teachers, and extracurricular leaders like coaches to see if the kid is exhibiting signs of ADHD. If a certain number of points is reached, they are ADHD and the doctor takes out a pad. However, the questions pretty much describe any fidgety overexcitable easily distracted young person, which is why it's diagnosed more often in boys than girls, even though the brain features seem to show up in both genders almost equally. Getting medicine is wildly easy therefor. However, it is much more difficult to get school accommodations for ADHD kids, and those generally require an expensive workup from a psychologist. The psychologists have in addition to interview and surveys run a series of tests. One of the older one is this light test...you have to sit there and see if you can push a button every time a light flashes on screen....it's not fool proof but it drives people with ADHD crazy. A newer one is a brain scan looking particularly at the front cortical regions. If we are concerned with overdiagnosis of ADHD and overprescription of medication, one would think we would want a gatekeeper of running this full battery of tests. The issues are that: 1) it's expensive (the brain scan alone is $5000 and generally NOT covered by private insurance) so poor kids would have a barrier to getting the help they need, and 2) parents who are trying to get their kids a leg up in school by cheating and giving them a little something extra for tests would be unhappy, which means less business for everyone concerned (from peds to pharma) and more complaints to deal with.
It's the same with gender dysphoria. I'm not up on what the protocols are but they don't as far as I know include a brain scan and generally rely on interviewing the subject. If we are concerned with an overdiagnosis of gender dysphoria, we are nearing a point where a brain scan could be added to the protocols if they haven't already been. But there are issues: 1) again financially equity as private insurance is generally not going to cover the brain scan, 2) the gender is just a construct people object to putting people into categories because it also precludes the possibility of a nonbinary person or a male who is slightly female or vice versa...they prefer to view it all as a spectrum with masculinity and femininity being social constructs, 3) the gender is pure biological people dislike it because they'd actually have to fess up there's something biological going on here to, which forces them away from the easy solution that boys and boys and girls are girls and forever will be, and 4) the government could abuse it by prescreening kids and removing kids whose parents refuse to nurture their trans tendencies.
