I donated all of my physical copies of things once I had a good system of doing it all digitally. It was one thing when the physical copies were what I used to enjoy the content, but when I realized I was regularly going to the digital copies of things I had physically, all of the shelves full of DVDs, albums, CDs, and books started feeling like little more than weird little trophy cases. In that context, the amount of space I devoted to them seemed silly.
