> Why do people buy movies digitally anyway? I can understand digital movies (they are convenient) but renting or streaming seems far more reasonable. If you truly want to own a movie as I suspect people who buy them digitally do, the only way to ensure that is to buy it on DVD/Blu-ray and rip

You're forgetting there's a slice of people who want to "own" a movie library but don't have the technical acumen to rip and/or (more importantly) host (consider that you'd have to stand up a Jellyfin server and have a good amount of HDD space -- I personally have 50TB).

Again, it's not _that_ hard in general but daunting enough and with high enough startup costs to dissuade a lot of people.
