Like you observed the damage of social media is not unique to children. So a more sensible legislation would serve to help everybody from the harm of social media, not just children.

Second, age verification systems have a lot to benefit from a government contract.

Third, social media and ad companies would for sure prefer a blanket ban on children rather then a more careful legislation which e.g. ban targeted advertising, or further regulates social media from harmful patterns.
