Buying something at a store isn't a good analogy. Uninterested members of the public being able to casually observe you buy something at the store is a perfectly normal part of society. A better analogy for today's internet is if you walked to the store holding a big sign with your credit card bill, texts to your friends, and a list of places you went today printed on it, and the street on the way was packed with people who were there for the sole purpose of taking pictures of that sign and selling them to whoever will buy. Targeted advertising would be the people who bought those pictures knocking on your door.
