You also seem to be under the impression that we have to wait until we have a perfect evidence base - even if it means people suffering unnecessarily. In reality all healthcare developments are based on an evidence base which is good enough - no evidence is ever perfect.
At the moment there is virtually no evidence base. People are suffering unnecessarily- they are being misdiagnosed and undergoing life changing treatment and surgery that harms their long term health.
No evidence is ever perfect, agreed. The evidence we have says this approach causes harm. I honestly can’t see why you’re so ok with that.
What possible benefit is there to a tiny minority that justifies the harm to so many? And don’t start claiming that people will commit suicide if they don’t get to medically transition - that is an outright lie.
I hope you have noticed that many of the most powerful advocates for child transition and prevention of puberty are middle aged men who went through a normal puberty, fathered children and had a successful career (enjoying good physical health). They survived, they didn’t commit suicide because they couldn’t medically transition. They might not have enjoyed the process of growing up but they had the opportunity to do so.
Therefore this is not essential ‘treatment’.
They are advocating for the essential process of puberty and full maturation to be denied to impressionable young people who are most likely (80%) to change their minds about ‘gender identity’ when fully grown.
