Let websites issue a "window.isUserOver(16)" call once and then move forward based on the response to that query.
This doesn't have to be perfect.
We agree it doesn't need to be 100% perfect. But it needs to be at least, like, 60% perfect, right? And unless you make it at least a bit hard to bypass, it will stop virtually no one.
To effectively keep adult content away from kids, it merely requires secure boot and closed app stores, which are already widespread. And they are only required on the devices actually given to kids, rather than every single computing device.
But this proposal has another problem: it's easy for a website to run isUserOver(n) in a loop to derive the exact age. And on a persistent account, it can be queried every day to derive an exact birthday! Which comes back to my main point that the only technical schemes we should be considering are ones where information strictly flows one way - the website/app supplies information to the browser/OS, which then [may] implement parental control policy. anything else fundamentally boils down to a mandate for identity verification.
This is unacceptable. If I own a computer, I expect to be able to build and run any program, either written by myself or others, without asking anyone for permission.
...I guess I don't really see the difference.
Closed app stores are widespread on some platforms but certainly not others, and I for one would really like them to not spread any further.
The RTA one was even pushed by the porn industry and is already in place in majors websites[3]
