Not to be a dick but I loathe this line of thinking..
It's like saying we should close all libraries and get rid of books since we can just have them digitally now. What happens if the digital copy gets corrupted? What happens if someone alters the digital copy and we don't know what the original is like (This has already happened)? What if you care about physically owning something? We need master physical copies of things.
People that think this way usually don't care about quality, pirate stuff or are just casual movie/music fans. I get the convenience but I see no benefit in digital outside of that and space limitations. I'm not going to let convenience trump quality and physically owning something.
