Since you ask, I know three. One guy I knew in high school transitioned to female around 2013, and requested I say "she." She was bullied a bit for it, not too much thankfully, but it was clear she was never comfortable with being male before. Another was similar but later.
It's different now and children are being encouraged to transition. They aren't just told that some are naturally uncomfortable with their gender, but that conforming to a gender is abnormal. Way more are doing it than before, and even afterwards are committing suicide at high rates. So I can't support it. I still think people should have the right to do it on their own dime, and won't judge them for it either way. I can't trust any studies on this anymore because it's become politicized and weirdly speech-policed. This isn't a unique or nuanced opinion, it's probably the majority one and I sound like the rest.

The range of human (mis-)behavior is extremely wide, so I wouldn’t doubt that some doctors and patients are doing what you fear here. I don’t think we should form opinions on such a broad situation on the basis of a few extreme people and situations.
The question I would ask is would you rather have more people suffer from not having care, than some people suffer from receiving care that they later regret? The latter is something that’s incredibly sad, no doubt, but it’s an intractable and tragic side effect of offering major medical treatments and interventions in general; the “false positive” aspect is not unique to gender affirming care, either in its existence or its magnitude. (The politicizing of the false positive is, though, because gender in general is incredibly politicized).
Gender dysphoria solved by one-way-door gender affirming care is quite rare (there are many intermediary steps people can try and ultimately be helped with), but education about the issue and the availability of treatment helps people like my friend. I think it’s pretty unambiguously positive to universalize the availability of that care in the same way as any other form of healthcare and education, because it’s genuinely the only way some people can feel comfortable in their skin. And although there may be problems with the standard of care, the standard for care can only improve with time and experience.
