If I buy a book it is MINE. Or, more broadly, when I buy something, I insist on it being mine. And once a thing is legally mine, I don't want any interference whatsoever from anybody in how I use it or whom I give it to or share it with. If I buy a Blu-Ray disc, the magnetic dents physically present in the matter that represent the ones and zeroes that make up the sights on my abyss belong to me. If a movie company want to restrict the use of their magnetic dents they better screen at theatres only as when I have the magnetic dents, I have the moral rights and the technology to reproduce and redistribute them. Also, in this day and age, disc sales probably mostly benefit disc sellers, and the best idea is to put your movie on YouTube/Vimeo/sth. after theatrical releases. Spinning disx with magnetic dents are by now primitive, and their use is to limit the consumption and sell peripherals. WRT books, I'm among those who prefer dead tree, because that's part of how I work, and I believe digital can't replace print books, but that does not mean no innovation is possible: Printing-press-on-demand should be introduced where I can order a printed copy of a book and then the seller prints one from a digital copy and sends me that. If book shops want to continue, they can just bulk-order print copies and put them on their shelves. Lots of money goes to intermediaries in book business and if you're not a world-wide best-seller, as an author you don't earn much if anything at all. And you're worse off if you want to be like Kafka or Calvino instead of J. K. Rowling.
