Ok, how long do you have to rip & copy the content as you desire? It is still reasonably a forever version. Before you bring up laws around keys, first consider that jaywalking in front of your house is illegal too. Again, it is reasonably a forever version.
Crossing the street in a residential neighborhood is legal in almost all of the world and increasingly legal in the US as well. Many major cities started with non-enforcement and some are rolling back jaywalking laws entirely.
Why should I pay to be treated as a criminal, when pirating is better in every way and costs nothing?
There is no option of "Pay for digital copy of show that permits format/time shifting and backup for as long as I want, with no DRM". Like GOG. Doesn't exist in the pay realm.
It seems like you're just adding more and more qualifiers until you can finally justify piracy to yourself. You can reasonably do what you want if you buy the disc. There's a good chance that's how the people you're downloading from did it. ¯\_(ツ)_/¯
I know it's not the point you're making but I would enjoy a post-apocalyptic post-AI movie where they pass on the lesson of the dangers of AI through an oral recounting or stage production of T2.
BluRay no, because your player's keys can be revoked when you pop in a new disc.
