Treatment for gender dysphoria aims to help people live the way they want to, in their preferred gender identity or as non-binary.
Some young trans, intersex, and gender non-binary people may decide to take puberty blockers after talking about it with their parents or guardian and a nurse or doctor.
I agree that there is nuance, and that there is a balance somewhere to make sure everyone gets the proper medical care that they need without a misdiagnosis that would lead to regret. However, I don’t think that the majority of people discussing it including myself are qualified to set medical policy.
The average person has no experience with trans healthcare. They just want to know that the kids are ok, because politicians have spent hundreds of millions of dollars exaggerating concerns to generate outrage.
While misdiagnosis is a real concern, medical experts and governments have already taken steps to mitigate that. They can always do better so they do periodic reviews to improve care. There are eligibility criteria and safety regulations in every country that I am aware of. There are also financial incentives to avoid being sued, and governments or health insurance companies often put up a lot of additional red tape to avoid paying out.
I just did a quick search for the NHS specifically and here is a list of what was required before someone underage could start treatment:
