> The only drawback is that being anonymous means it's easy to resell tokens.
That’s a pretty major flaw. These tokens will be sold with markup on black markets, rendering the whole system unfit for its intended purpose.
Additionally, in line of drawbacks, buying porn scratch cards will be stigmatised, because everyone will (think they) know what you’ll use them for. Are you comfortable doing it in front of your teenage child, neighbor, crush, grandma, or spouse?

And yet we have functioning asymmetric cryptography systems that enable secure encryption for billions of people, despite malevolent actors having a clear incentive to subvert that, much more so than age verification tokens.

This is happening right now already, in a scale hardly imaginable.

Black markets catering to minors aren't very large or profitable. No adult needs to buy from this black market. How big is the black market for beer for teenagers? Yes, some reselling will happen, just as minors sometimes get alcohol or tobacco from older friends and siblings. Prosecute anyone involved. It doesn't have to be perfect. It just has to be good enough without sacrificing privacy.
