Nothing to hide?
If the fact that you have "nothing to hide" makes it ok for others to spy on you, does that mean that, since you don't need every room in your house at all times, I can come and use those spaces when you don't need them?
If the fact that some people don't want to offer their life on a platter to others implies they have something (bad) to hide, does the fact that you lock your house when you are not in it make you a selfish, exploitative person? After all, I could use your house while you are away, and you wouldn't even notice someone was there. You have nothing to lose!
