I always try to just these things based on physical analogies. The clear analog for visiting an ecommerce store is walking into a physical store with a shopping cart. Maybe the physical store has cameras or some other way they track people. In any case they probably aren't watching every single customer to determine which aisles they walk down, if they pick up an item without putting it in their cart, etc. Let's say they are doing that though, for the sake of analogy. It's strange to me that people are ok with that, but let's move on..

Now, since an adblocker doesn't change anything anywhere except on the end user's computer, the analog should be something on the customer's person, or some part of their behavior. So let's say the customer tries to avoid identification by wearing a hat, and they purposely grab every item and put it back on the shelf to mess with the data about their shopping habits.

Do you think it makes sense for the cashier to refuse to checkout anyone who is wearing a hat? Or if they spotted someone who picked a few things up without putting them in their cart?

Because I sure don't.
