Sure but the license isn’t to purchase those products. There is no licensing for them even though you typically use your license to prove your age. You can also use a passport or military ID or a standard state ID that looks exactly like a license but requires no test. A liquor license is to sell, not purchase. And for the record, I like your ideas but using something like a medical card for purchasing weed would have been a better example.
