> But if you want a legislative solution, there already is one (COPPA) which prevents people under the age of 13 from joining social media.
Nothing (besides parents) can prevent people under the age of 13 from joining social media. The kids just lie about their age. Everyone knows how to lie about their age to get something they want, from the time they're in kindergarten.
And I’d suggest that’s absolutely the way you want it to be. The consequences of pushing a full blown KYC regime on all social media are pretty dystopian.
The value COPPA does provide is as a tool parents can use. If they report their underage children’s social media accounts, they will be removed. But of course they still have to actually do the parenting, which is how it should be. I think you shouldn’t want government to takeover those responsibilities for them.
