So we are ignoring jurisdiction? ... Well... even if we ignore the possibility of an infinite universe, tracking hundreds of thousands of legal systems and species biology (what is intoxicating to whom, the cognitive self-development thresholds, how much of a substance one may serve to whom) and being able authenticate/verify an ID (we have photo-ids, but maybe others are different)... like a slime-species that identifies each other by smell... or taste... I'm confident that for any interesting set size, this would actually be an unsolvable problem.
