I get the point, but it's not a good way of defending it. The ADHD medication might be okay, but here is framed as an exaggeration, and the other one is not good.

Furthermore, many of those interventions are detrimental or at least dangerous. Mine was orthodontics and it ended terribly; today, I would need a surgery to correct all the damage caused. While I was a difficult case, it's not uncommon. In recent years, braces are being reconsidered as they alter a developing skull, often atrophiating something while repairing something else. Sports in childhood can have an impact in adulthood. This one I'm also living it closely as my mother was one of those girls inspired by Nadia Comăneci to start gymnastics. Today, she's living a hard late adulthood.

We've normalized not listening to children and thinking of them as our properties. Medical interventions (I literally pointed out the problem with my treatment and I was ignored) or the lack of them can be a sign of this. We need to balance their developing cognitive abilities with their autonomy, not shadowing their autonomy all together. That's the argument. Telling people "things are already done, so what's the problem?" is fallacious at best and counterproductive at worst.
