To enter a movie theater, you have to buy a ticket. If you don't, you're barred from the entire class of activity of movie-going.
Where is the difference?
Where is the difference?
For one, I don’t have to buy a ticket. Many theaters participate in programs where you can get a ticket as a reward for other activities (credit card points, eg). The ticket sale is determined by the theater, and is not part of a government supported scheme to prevent some people from ever seeing a movie in any theater, ever.
Finally, the sale of a ticket is necessary for the operation of many movie theaters. It is intrinsic to the business model. The nightclub could operate the service, and even work with ban lists without the centralized biometric database.
Going to see a movie is obviously not unrelated to buying a movie ticket.
