Let's translate this to brick-and-mortar: > What if I want to target women who recently bought Chanel perfume? How would I go about doing that unless I do video surveillance and face-recognition targeting? Suppose a woman walked into a dress shop, and the clerk said, "We find that our $LINE line of dresses over there works really well with the Chanel perfume you just bought." Do I have to explain why 1) people think it's creepy, and 2) why people think you don't have a right to do that?
