It's obvious we're moving in a direction where we are going to get these restrictions in one way or another, and this is the only way I've come up with that doesn't come with serious privacy implications.
Most importantly, this solution would be simple for anyone to understand. You don't need to be a cryptography expert to understand there are child safe devices and then there are unrestricted devices for adults.
If most adults would be convinced there is an issue, one probably has enough lock-down modes even nowadays, not sure it is a "technical" problem.
I can also see also large support for uploading ID to various services when talking about kids, but when you re-frame the question to adults, most seems to really dislike the idea immensely.
Sure there will be children with access to unrestricted devices, just like we had kids with porn mags hidden in a forest somewhere back in the day, or how that one sketchy guy was buying alcohol, etc. But I think this is an acceptable level of risk for whatever harm people want to prevent.
Consider that even with something as divisive as covid lockdowns and vaccines, the overwhelming majority of people complied with government instructions.
There are a minority of people currently refusing to vaccinate their children properly, and their fucking around is being found out with measles outbreaks in various countries.
Why would this be different? Why wouldn't it be a minority of parents permitting their children to drink, to smoke, to use unrestricted computing resources?
Are you saying that kids now buy their phones with pocket money without their parents knowing?

It’s not obvious, it’s just sad. I still hope reason will prevail in this.
I keep thinking that computers that are actually made to be good for children should be a thing. Perhaps like "A Young lady's Illustrated Primer" ( https://en.wikipedia.org/wiki/The_Diamond_Age )

That describes something very similar to what the OP suggested.
> Essentially, this is a cross-platform, cross-device, government-led parental control system that has been painstakingly planned out by Beijing.
> The rules are incredibly specific: kids under eight, for instance, can only use smart devices for 40 minutes every day and only consume content about “elementary education, hobbies and interests, and liberal arts education”; when they turn eight, they graduate to 60 minutes of screen time and “entertainment content with positive guidance.” Honestly, this newsletter would have to go on forever to explain all the specifics.
We don’t do this in free societies. Let the parents decide.
Centralized power and being unafraid to use authoritarian tactics. Also the general cultural ethos of the people.
China is much more socially conservative, and less likely to abandon their kids to latest thing.
I don't know about Korea but if memorizing an ID number works, then that's just a badly designed system.
I'm not sure what your argument is really, unless you're saying there's technically and absolutely no feasible way to securely verify the age of a person before allowing them to access an online service (even if you allow the government to be authoritarian)
the actual users of each simcard did not have to identify themselves. so at least then it wasn't about age controls, but it obviously would allow tracing the owner eventually.
