In fairness (i.e. looking at the data with an open mind), social media does seem to be the cause of (or at least strongly correlated with) a bunch of ills.
Either way the solution again is not age gating, it's real meaningful data privacy laws that if enacted would have a huge effect on many companies today.
This is exactly what I mean: you've rocked up and started talking about something else entirely.
How do data privacy laws prevent a 14 year old from being cyber bullied online or consuming influencer content destroying their self-esteem?
This is (in the most politically neutral way I can put it) what people who want social media age checks are talking about.
