That's quite an elaborate system. It goes through a lot of gyrations (not the least of which is inventing a whole new type of crime and passing laws about it) and doesn't sound even as strong as the age verification "required" to buy cigarettes in the US. I'd think "welcome to pornhub. Either log in or do Privacy-enhanced Age Verification by Auth0 (TM)" would be a lot easier to get off the ground.
