I'm not too worried. I live in California, and our regulators would block most of what you suggest. They already do for insurance -- they block insurance companies from a lot of data that they consider discriminatory.
The moment a politician was affected by this data collection in a negative way, it would probably become illegal.
Hell, it's illegally nationally to share someone's video rental history because a politician got screwed out of being a Supreme Court justice when their video rental history was released.
Your purchase history is being sold to companies outside California jurisdiction. Aside from video rentals, all of your consumer data is fair game for middlemen to peddle amongst themselves and build a profile about you. They lobby to keep it that way.
