I think I understand what you are trying to say, however...

> I don’t think anybody is saying “make Facebook illegal” ... consider whether such machines have any place in a healthy society.

That sounds exactly like a moral crusade. You don't want to make it illegal, but would like to consider if it has "any place", and also someone will have to define "healthy society". If you asked people in many places and times (if not most), they'd tell you homosexuality is an abomination that has no place in a "healthy society". Even at present, some people literally treat it as a disease in need of a cure.

And yes, I think prescription drugs should not be a thing (well, prescriptions are fine but if I want to buy metformin because I think I'm smarter than everyone else I should be able to do it and prove myself right (or wrong).

Tobacco is a perfect example for me personally, because I dislike it, so I feel good about forcing everyone to not smoke. On the other hand, it hurts almost entirely the user, so the only justifiable restrictions would be the ones where the user is imposing costs on others, e.g. charging them more for healthcare... I like the advertising bans, but I would have also liked e.g. never having children around, via e.g. banning them from all restaurants and gyms. Doesn't make it justified.
