On that last sentence, I wouldn't say "something to hide". I like to think of it in terms of highlighting the difference between secret and private. There are lots of things that I'm not ashamed of, or protective of for the sake of my safety, but still have a totally valid desire to keep private. Going to the bathroom isn't secret, but it's still private.

"Something to hide" specifically makes sense in the context of the phrase "if you've got nothing to hide, you've got nothing to fear".
