I have full control of the movie/tv show. Where and how I use it. I can rip and control how its put on my digital devices. Bitrate, FPS, aspect ratio, etc. And not be tethered to net limits or when it fails. I don't have to log into nothing. Simple as that. I can care less that I can play things faster or have to swap discs. If companies stopped blocking the buttons with all those dumb startup ads and warnings. Discs would equal file startup. Games, I have all my past system connected and running. And normally never rebuy anything.
Also, the logging into my account on friends system, is not an option. Unlike most people. I do a 40+ random symbols PW I can't remember. It's written down. I could never log into my account without bring that paper. Not conveniant.
