Physical vs. DRMed digital is not a dichotomy. Personally for books, I do prefer paper ones - and mostly read in my language on paper. However, pretty much all non-fiction I read is in English, and getting it in paper would cost a fortune (English books are not sold here that much as we’re not an English-speaking country, and shipping would likely cost more than the book itself).

As for movies and music - it’s all digital DRMless as well, unlike books, there isn’t even a functional difference between a file from a tracker vs. a file from a DVD, except that you wouldn’t have to throw out a perfectly good disk after ripping.
