You don't foresee a black market of "no-age-audit" devices? How do you prevent that? Well, one way is to use the secure enclave and write the birthday in it so that it cannot be tampered with. How is that written? who writes it? Who verifies the ID?
TX passed a law stating that adult sites like pornhub must verify age. I hope you understand what "verify" means in this context. It isn't "i promise i am over 21 or 18 or whatever" - because if that worked, TX lawmakers wouldn't have made the law say "verify" https://journals.law.unc.edu/firstamendmentlawreview/screeni...
In the future, casual dismissals are viewed negatively.
