Yeah, I can absolutely see the controlling aspect. That said, schools, parents and health institutions already provide education geared towards positive health habits, which you can argue is similarly controlling.
I’m not suggesting hypnosis should be forced on everyone at birth - it’s not something I’ve ever considered for myself. It’s more of a shower thought. I was wondering why it’s not more widespread as a preventative mechanism if, as seems to be the case through various studies, it can have a positive effect on the reduction of pain, addiction and various psychological issues.
I really don’t agree with your last sentence though. “Fixing” problems before they arise is exactly why we, particularly governments, already spend millions on the promotion of wellbeing and heathy lifestyles in order to prevent health issues in later life.
