> You conflate the European change in medical policy, which still permits the use of puberty blockers to treat gender dysphoria, with American legislative bans that do not permit that.

No, it largely does not. Most European countries at this point, if they do permit blockers at all, only permit it as part of a clinical study, not as routine treatment for gender dysphoria. This excludes all but a slim minority of (if any) patients. Pointing out that it's still legal as part of experimental trials is a nuance that doesn't affect the >99% of patients that aren't part of a trial, and thus cannot be prescribed these substances.

Your linked publication doesn't actually interview patients who've worked with clinicians or otherwise try and dig into real-world evidence about what this clinical practice does. It's just one author postulating her opinions as fact, with no effort to back up her claims with evidence.
