Even data "hoarding" can be a problem for someone if it begins to consume their life. Sure, the physical consequences aren't as severe as hoarding old junk in your house, but it could possibly become a physical and mental problem for someone. Sure sounds like that is not the case for the OP, as it all sounded like a bit of a joke to begin with. But I'm sure you could find someone for whom data hoarding is a real problem that negatively affects their life if they feel compelled to constantly seek out stuff to archive and begin filling their house with storage media.
