Many of the responses given to this question are fairly weak, eg. "but what if you don't want people to see you naked?". Invasion of privacy affects someone's dignity, sure, but it's the fact that it makes one _politically neutered_ that's the actual issue and is harder to explain. Here's one response: "Imagine if you ever wanted to join the Occupy Wall Street movement or something like that. All of a sudden the government, who will now see you as a threat, can go through everything you've ever done and hold it against you. Remember that one time you pirated a movie? Jail time. Remember that one time you experimented with drugs? Jail time. They will dig up something from your past and use it against you. Oppression is not a theoretical idea and not only an historical problem. Having all information about yourself available essentially makes you politically neutered." I'll be putting together a set of real-world examples to further emphasize the point.
