The current systems are not ineffective because they’re optional, they could be more effective and stay optional.

I also don’t mean “mandatory” as in “the software manufacturer must implement parental controls” like the Colorado bill. There only needs to exist one decent operating system, one decent messaging service, etc. with good parental controls; parents can use those technologies and block the others. Although regulators could pressure specific popular platforms like YouTube, and maybe that would be fine, I think it would be better to incentivize and support add-ons or alternatives (e.g. kid-safe YouTube frontend).
