I think an important consideration about the I've got nothing to hide camp is that they don't need absolute privacy. The argument about handing over passwords or writing letters on postcards falls flat because the person who's "losing" privacy can agree that a medium isn't private and respond according. Not everyone needs 100% privacy all the time.
