Other people have already responded to you, but I think they've fallen into the common trap of assuming that privacy is about having something to hide. Yes, the data collected might be leaked by poor security, and yes, you might not want your neighbors installing cameras in your shower, but that's not the point. This is an excellent paper on the problem: https://papers.ssrn.com/sol3/papers.cfm?abstract_id=998565 https://papers.ssrn.com/sol3/papers.cfm?abstract_id=998565 In short: privacy is not about hiding things. It's about an exchange of power. A government with more information about your life is one with more power to make decisions about you. There are many reasons to oppose this: * Chilling effects. People may be more afraid to conduct legal activities for fear they will be misconstrued and used against them by the government. ("Sorry, you can't fly anymore.") * People are powerless to fight decisions the government makes on their behalf, because they do not know what data the government has collected, and all of it is secret. It's not Orwellian; it's Kafkaesque. * Small bits of information gathered through surveillance can turn into much more interesting information about a person combined. You might not mind revealing each individual tidbit, but what about the picture they paint when combined? There's more the the argument, which you can read in the article linked. Privacy is not just about secrecy.
