These laws aren't about children, that's just a talking point to sell laws that tame the potential anonymity of the internet for private profit.
If American society gave the slightest shit at all about our children, we wouldn't have literally starved our K-12 system into utter ruin for over half a century to cut the taxes of the corporations and already rich assholes killing the planet and those children's future on it for private profit. We wouldn't then say selling public education to for profit industry in the form of charter schools is a solution.
The United States doesn't give a shit about its children. Not one tiny bit. Now our beloved economy? We'd throw all our (non-wealthy) kids into a fucking volcano if Wall Street told us it would protect that.
