Agreed. Even when you "buy" a DVD or Blu-Ray, you are actually just buying a copy of the media with a limited license to use it for certain purposes.

The license you bought with the disc doesn't extend that far. Whether you "buy" a movie via a disc or a streaming service, you're really just buying a limited license to display the movie along with either physical or digital delivery.
