I agree with everything said above, except this:

The next question is, what are you tying to protect?
This is similar to me asking you why you are wearing clothes inside of your house? Are you afraid of a mole? Is there some hair you don't want people to see? Moral of the story: Just because people enjoy privacy does not mean they are hiding something. Privacy isn't just about hiding, it's a psychological state in which one can feel comfortable being alone with themselves.
