You may say that credit and debit cards do this already (and they do), but you can still pay cash in public stores. Of course they can track you with your phone's bluetooth identifiers, facial recognition, etc., but why as a society should we allow public businesses to require this?

But none of the websites should be allowed to pull the fast one on their visitors by stealing and sharing visitor data to other entities.
