Sorry but there is nothing noble or superior about buying and keeping DVDs. That’s just materialism. I had a collection of 100 Blurays a few years ago. Eventually I sold everything when I realized that owning pieces of plastic that get dust on a shelf didn't bring me any joy. I enjoy movies at the theater or on Netflix as much as movies on physical support. And movies are not going to "vanish" if you stop buying physical copies of them on Amazon. Conserving movies is the job of film archives. You probably have one in your country that offer screenings of old movies. Or arty/independent theaters that offer the same kind of content.
