I generally agree with what you're saying, and I came here to post my opinion, but then I wondered, is the concept of "nothing to hide, nothing to fear" something new or not? Pre industrial times, I would assume that people were more private in general, and a desire for privacy was more acceptable. But I really don't know...my impression is that this force openness popped up especially around WWII when propaganda and espionage were immediately deadly things.
