I treasure all my entertainment material (books, CDs, DVDs, etc.) because of their actual content and not their physical condition or material value. And I feel really glad when other people get to appreciate them too. I can only read/listen/watch them so many times. So I don't mind some nicks here, some scratches there (and in the case of books, I even endorse a good battering), especially when the person who borrowed from me was able to really enjoy what I lent them.
Years from now, and when I pass on from this life, they're all mostly going to either rot, get lost, or become obsolete anyway so I might as well spread the wealth (and the pleasure) around while I still can and while they can still provide it.
