There are situations where it's advisable that people not only obey the law, but they obey it in a publicly verifiable way.

And how much effort must the seller make to obey the law?
1. Ask for an ID
2. Check the id has the same biometric data as you have with a retinal scanner
3. Check the id biometric data and its tamperproofing.
How much faking are 17 year old agent provacteurs allowed when buying booze? Can they just ask for booze or are they allowed start using fake id's the way all the ones who are not gathering evidence do? If they are not allowed to start faking id's they will be easily spotted. If they are it seems to be getting a bit hard on the off-licence.
