Right, I don't think I've ever actually seen anybody make the "nothing to hide" argument. Maybe it was used more commonly in the past, but I only ever see people pre-emptively attack it without prompting. It seems to be a special case of a straw-man argument: a no-man argument. It's not the only such example, but it seems to appear without fail in the top comments in any discussion of privacy issues.
