The ban needs to be enacted legislatively after market creation.
What counts:
ban on distilled spirits only
ban for people born after a given date (simmilar to NZ tobacco ban)
extremely restrictive personal quotas (<20% average consumption prior to enactment)
What does not:
increasing drinking age
restricting sales to a small number of outlets
supreme court decision finding the sale of alcohol unconstitutional
anything a country with a theologically driven legislature does
an attempted ban that gets legally overturned before coming into effect
