ELI5: How can Netflix acquire the rights and permission to ship DVDs of a movie, but not acquire the rights and permission to Instant Stream it?

I understand why every movie ever made isn't on Netflix, and I understand why new movies don't immediately appear on Netflix too. What I don't get is why would a distributor of a movie would agree to let Netflix ship out their movie on DVD but not allow them to stream it.

Why indeed. What's the truth is that the digital streaming rights are negotiated completely separately to the DVD Rental rights, and movie studios see streaming as a threat to their big-ticket DVD sales, that's why hardly any new releases get authorized for streaming. Understand that Netflix WANTS to stream everything they offer, but if the movie studios don't offer the rights, they can't. Netflix's hands are tied. Understand?
