Thanks for taking the time to answer. In my view, it's easy to legislate away at least 50% of the harm. Not perfect, but much better than 0%. This would be banning recommender systems and infinite scroll feeds for platforms above a certain size ("gatekeepers"). I'm sure there's a number of loopholes, and you might still believe that even this kind of measure would create more than it solves.

On the supermajority bit, in more and more countries there's already a supermajority for banning phones from schools, more and more for banning it for children altogether, and so on. I think that's a clear sign people would actually be in favour of quite a lot of measures to tone things down, like the one I mentioned. Total bans I wouldn't vouch for.
