Yes, this is one of those game theory traps like the prisoners dilemma, because it requires coordinated action across a large group of people. Unfortunately the lowest common denominator parenting is not able to handle the problem, because the parents don't understand the situation, are addicted to platforms themselves, and just generally don't have the necessary skills.

Government regulation is a ham fisted approach that risks unintended consequences / secondary effects, but it is generally good at breaking the game theory traps because it changes the playing field for everyone. That is fundamentally why we have government at all - to solve coordination problems.

The government can also act as the faceless bad guy who 13 year olds can get mad at while parents shrug and say “sorry that’s just the law”.
