I would be against a law that did not allow for different kinds of standards and situations.

When I was a kid, from age 3 to 14, I was in a lot of gymnastics tournaments, dance recitals, spelling bees, and modelling jobs that put me out in front of crowds and in (regional) tv advertising and newspapers. It was before these things were called "content" online, but large parts of my life were exposed to the public. My parents protected me from weirdos and negative comments, and they put my earnings into savings accounts that paid for undergrad and grad school. A law that prevents childhood public life would have prevented me from competing in events I was good at and from doing an easy job that paid me well and provided opportunities a lot of other people don't get.

But there are also attention-seekers who do not care about their kids one-tenth as much as they care about the dopamine hit they get from likes...
