I’ve always struggled to understand why someone would pay the same price (or nearly as much) for a strictly-digital copy
Convenience. I’ve been in situations where it seemed easier at the time to just buy a movie on Amazon. For example, if I’m on vacation or a work trip and I really want to see something.
But that was before I learned about which sites were safe to use for streaming and had high quality content.
Also, I’ve learned that my library still has a large DVD collection, so I apprise myself of that.
