A highly specious argument.
The idea that personal papers should be muddled with creative works that have been published is an unfortunate consequence of European ideas about copyrights. This includes the daft notion that every scrap of paper is precious.
Private papers should remain as such and any attempt to drag copyright into this discussion is merely clouding the issue for the benefit of a miniscule set of corporate interests and their misguided lackeys.
Any modern discussion on privacy needs to start by rolling back copyright concepts to 1783.
