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?

Do you really not see the difference between having to pay for a service and having to upload biometric data in a centralized database under someone else’s control?

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.

> activity unrelated to what you opted out of

Going to see a movie is obviously not unrelated to buying a movie ticket.

The difference is that buying a ticket isn't marketed as "opt-in".

This comment cannot be done in faith. Buying a ticket versus buying a ticket AND being profiled by all other venues are clearly two different things.
