I haven't had a disc drive in any of my PC for a decade. I bought a USB DVD reader just in case, it's somewhere collecting dust — I've never used it. Why do you want one in a console?
And anyone that does, they will simply pirate the media anyway. So no loss on their end.
Another reason I like it is because I prefer to have my console games on a disc, this way I can share it with friends and I don’t have to be at the mercy of people like Sony who is not afraid to remove access to something you paid for.
