But there's nothing stopping me from stopping the DVD halfway through.

And who's to say I'm being drip-feed these movies on autoplay? What if Ghibli had their own service (please no, not another one lol). I would have to make the deliberate action of going to their platform, searching for the movie I want, and clicking play.

I don't see the lack of streaming as preserving value, the value should (and definetly does imo) come from the movie itself. The animation, the story, the colors, the music.
