If that’s the nearly infinite wiggle room we’re playing with then I’d say what about Adult and Child versions of phones? You have to flash your ID to the clerk to buy an adult one, like buying cigarettes at a gas station, and then you get to do what the internet offers. Child phones - let parents and governments come up with whatever they want to block. The phone autoupdates in the background with the blocklist, the device can’t do those things. There ya go. Each person and family gets to make their own choices and nobody has to give an ID card to PornHub or a company that literally exists to harvest your information. Win-win?
