You should be able to choose what's age-appropriate for your kids. Giving them access to e.g. "PG-13" media when they're 9 isn't the problem. Giving mature kids unrestricted access isn't a problem. The problem is culture:

- Many parents don't think about restricting their kids' online exposure at all. And I think a larger issue than NSFW is the amount of time kids are spending: 5 hours according to this survey from 2 years ago https://www.apa.org/monitor/2024/04/teen-social-use-mental-h.... Educating parents may be all that is needed to fix this, since most parents care about their kids and restrict them in other ways like junk food

- Parents that want to restrict their kids struggle with ineffective parental controls: https://beasthacker.com/til/parental-controls-arent-for-pare.... Optional parental controls would fix this

Did you mean "mandatory" parental controls? All current systems are optional and as you describe they are frequently ineffective, so not clear why keeping things like they are would be different.
