I don't see how the control and enforcement of "social media age verification" solves for the "people who are unable to stop... under their own willpower." My grandparents are more addicted to the phone than I am. Taking the superlative stance of social media being the "most advanced behavior modification schemes ever devised by humans" wouldn't the correct regulation be some sort of threshold of consumption (screen time limits per application), or rehabilitation for those that have crossed a line into psychological addiction? I imagine the easiest, assuming you see "the algorithm" as the problem, would be to ban selective algorithms and force timeline-based feeds or the like.
