profiling can also be done with knowing all the facts about the people
around you. eg: the percentage of dogfood sold in your neighborhood is
higher than average. Then one can assume that you too might have a dog
(without knowing that you buy dogfood).


Bunk. Assuming stuff about me doesn't invade my privacy. People had done that for centuries. It is called gossip.

That depends on how reliable the assumptions are, and what the
consequences are. With networked computers doing the assuming, and the
consequenting, you may find that your life is "personalized for your
benefit" by entities over which you have no control.
