That's just speaking for the fact we need a better way to distribute HD movies than a need for optical media. For example, if there were some sort of DRM that would allow you to purchase and load a digital copy of a movie at a retail location (target, 7-11, gas station, whatever) onto a USB storage device. Transfer it to whatever device at home (media set top device, computer, etc.). The DRM license would allow for reloading that movie at whatever location in the future should you delete it at home. That's assuming you don't have broadband without caps where you could just download it at home.
Would save millions or billions of tons of waste used in producing optical media as well as all those discs gathering dust. There'd be an upswing in flash devices or hard drives, but since those would be reuseable, it wouldn't generate nearly as much waste.

Maybe true, but even right now copying 50GB of data takes a lot longer than grabbing one disc off the shelf, paying, and then going home. Right now I still consider it more likely that streaming will eventually reach the quality we need, and then we'll start seeing discs slowly disappear.
