I'm also extremely concerned about what social media is doing to children's brains and how that manifests in their adulthood. I'm also concerned about how they affect adult brains, because I see it negatively affecting the decisions of even seniors.
But it's not "as simple as that". These sorts of solutions have serious consequences on civil liberty, privacy, security, affordability of general purpose computing, fair-use access to uaeful information, restrictions on state-sponsored information control, etc. This isn't a black-and-white problem.

Just as the problem is not black-and-white, the solution isn't either. There are a lot of steps to try before that. One is to try an awareness campaign among kids about the dangers of social media. It's a bit arrogant to believe that kids don't care about their own safety. Another is to assist parents with supervision and parental controls. Instead, they just jumped directly to the nuclear option. This kind of rhetorical framing of the opposition hides the likely nefarious intent behind such despotic measures.

You paint both parents and politicians as naïve individuals. There are plenty of parents who can see the problem, since they're Gen X and millenials who grew up observing the change. Meanwhile, assumption of incompetence among politicians is defeated by the fact that much public debate about it is missing here. And the fact that multiple states are coming up with similar bills, indicates the influence of lobbyists. Besides, the US politicians are not exactly known for defending the citizen's rights against corporate interests. They deserve a heavy dose of skepticism and criticism, not the benefit of doubt.
