The laws being passed target exactly the wrong thing that wasn't a problem. They should have been passing "duty to care" laws aimed at social media companies not "give me your age" laws.
I may have missed it, but almost all these laws being passed for this issue have been pretty much solely around data collection rather than modifying the behavior of the worst businesses in the game.
It would be like seeing a car wreck kill a bunch of pedestrians and then passing a law that pedestrians need to carry IDs on them.
