That's just a means of banning social media for everyone, which is even better than banning it for teens.
How so? Do you believe the average person will think twice when TikTok asks them to submit a picture of their ID? No, they'll do it without a second thought so they can go back to mindlessly scrolling through the slop.
The ones who will think twice are exactly the sort of people these laws are intended to punish: the dissenters, the wrong-thinkers, those who must be silenced. Either they choose not to verify and cease to use social media (successfully silenced), or they allow their wrong thoughts to be tied to their identity, such that they can be identified and punished accordingly.
No, it's a means of removing anonymity so promoters of ideologically unsound sentiment can be identified.
