Buying physical medium and digitizing is good. It bothers me that much of my large book collection and movies and TV shows I have bough are on streaming services. If I stop paying every month and how ever much they decide they want now then I lose what I have "bought". Since I bought I feel no remorse if I find a digital copy in the usual places and download that.

As an extra bonus my thousands of books and hundreds of movies and series take up far less space and are easily backed up. I am doing this to my physical books bit by bit too. If I can't find a digital copy I am thinking of buying a reasonably decent scanner with good OCR.
