I may not have been following this topic closely, but I do like this suggestion. Truly anonymous age tokens should be a thing. However, we're not going to get that because politicians would just say it is open to abuse. Anyone can go to a liquor store and supply alcohol to minors. The same would apply to anonymous age tokens. I don't know if it would be a big issue in practice, but it will in the minds of politicians.
