Earlier quoted context omitted.
I would pay a non-trivial amount for a service that 1) bought a blu-ray on my behalf, 2) ripped it to a file, 3) gave me that file to download, once, and 4) after confirming I had it, shredded the blu-ray. I don't want to copy things and distribute them to others. I want to have one copy that keeps working indefinitely and doesn't go away or fail to follow me across systems.
That's still illegal. A company tried to do that with an array of DVD players.
Debatable. Streaming content to someone while keeping the physical media is debatably public performance. I'm not sure if anyone has tried to make the "first sale" argument yet.
