Most people do have some things to hide. I think people would be extremely upset if police started buying real time access to GPS data from your phone in order to more efficiently locate speeding cars (instead of setting up post somewhere and wait for a car they feel is speeding "enough to be worth it", or eventually get board of the spot, and just go after one of random cars that is speeding slightly.) People sometimes do things like planning a surprise for a loved one. sure you might not really care about hiding this from the government, but hiding it from some corporations can be important. Imagine planning a surprise party for your spouse, only to have the surprise ruined by all devices in the house starting to show ads for something you searched for. (I've literally seen this sort of thing happen. I've even had things my parents who live multiple states away look up start showing up in my advertisements, because ad-tech companies correlated a unique identifier for one of my devices with unique identifiers from their devices, because both shared a public IP address for a while when I was visiting a month or so previously.) People generally have many things they would not be comfortable being generally known. Exactly how much money you make. How much debt you have. How many things you bought out of state that you failed to declare use tax on. The fact they they sometimes use piracy sites or torrents to watch movies or shows from services they don't subscribe to. What type of porn they watch. The list goes on. Once again, many (but not all) of those are things people don't really care if the government knows. They may only want to keep this information from people who know them, or even specific individuals. But these are still things to hide.
