For 99% of what happens on the Internet? No. No, we can't. That would be malicious fearmongering.

malicious fearmongering? all that most people know about "the internet" is facebook, instagram, tiktok and the other corporate propaganda machines. by popularity, that is absolutely 99% of the internet, and not "the renaining 1%", as you are portraying it.

Educate parents so they can prevent their children from accessing that harmful 1%

wasn't that exactly what I was saying? providing tools in the freaking operating system to limit what your kid can do? but downvote me to hell because I'm clearly wrong and that will surely fix everything!

But this age tracking shit will do absolutely nothing to protect children,

you know what it will do? with proper OS level integration, with programs taking it upon themselves, easier presets for the kid to only access age appropriate things. age brackets, that's it.
then even the web browser can manage the limitations natively, either with filterlists like what ublock uses, or when the visited website self-declares its category.

Its only purpose is to control access to the Internet,

how in the fucking hell will it control access to the internet when the local system administrator can change the age bracket setting in the OS.
