I do not disagree that tracking happens. What I disagree with is your implication that the scale at which it happens is irrelevant. It isn't. A security officer tracking me in a mall or a secret shopper recording my actions constitutes a single data point. Mechanically recording of all my movements within the store by tracking my cell-phone removes entirely all of my anonymity.

This kind of stuff is creepy, Orwellian and it can fuck right off.
