Also, Google Play movies has an offline option, which is not the same experience as DVD, but seems to fit you bill: https://support.google.com/googleplay/answer/2851696?hl=en
If it makes you feel better, pay and then "pirate".
As long as Netflix & co keep giving the frankly ridiculous excuse of preventing piracy as the reason I can't stream 4K content with mpv, I'm going to remain very reluctant to give them my money. (I'd be much less reluctant if their anti piracy efforts actually worked, but they don't and they never will)
Why do that, when you already give the creators exposure? Surely an lighting technician and a sound engineer can pay for groceries in exposure, right?
Perhaps those lighting technicians and sound engineers should just leave the industry that insists upon making it ridiculously difficult to give them money, if I want to get a high quality digital copy of a movie or TV series the only option is logging into BTN or PTP and grabbing a bluray remux.
Hell, often these communities have content available at a significantly higher quality than any of the official releases. See DIMENSIONs 20GB mad men episodes for example.
I personally just frequent the cinemas, and try to pay for the few TV series that I can, despite it often being impossible here.
