In addition to the reason already mentioned, one of the most important reasons privacy is necessary is how people - especially children - discover new aspects of their own identity, personality, and interests. Children will experiment when they think their parents aren't watching. Freedom to experiment and explore their interaction with the world is obviously very important for children, but this use of privacy never really goes away. Consider if you wanted to learn an instrument but have never played music before (or any other difficult skill). You probably want the freedom to practice badly for a while. If you had to practice knowing people were watching you, would you feel as free to experiment learning this type of skill? Problems of abuse and power are obviously very important concerns. However, I believe the chilling effect surveillance has on people will cause a major shift away from people experimenting with learning new things and exploring their hobbies will become an insidious, system damage to culture and social liberty.
