Everyone agrees kids shouldn't be on social media. Some people think this should be done by your phone asking if you're over 18 when you set it up, which is one way to go about it. Some other people hijacked this proposal to make your phone verify if you're over 18 because they want your identification.

And then most people just want a ban. So politicians, working as they often do in a technical vacuum, treat it like the other things we age gate.
