[usrbinenv]

Of course, it's pretty easy to see through this: introduce law in a few states, but now every OS needs to comply and because it's hard to actually tell which country/state user is in, they'd just have to implement it for everyone. It will be verification through some third party. You can opt out, but then major websites will be forced to deny you access (by, for example, Cloudflare) unless your OS provides a verified and signed certificate of your age. Then it's done: nothing will be possible without an ID, which means no dissent will be tolerated.
