I think this could be rephrased as people don't consciously download things to keep forever. Whatever device you're watching on will cache anything you've viewed for a while so it doesn't need downloading again, and I at least make quite heavy use of the ability to save things for offline viewing on train journeys. What I don't do anymore is to download video or music and then just keep it around on a hard disk just in case I want to watch it again. At least in my case storage is actually far more expensive than bandwidth, both in monetary value and time spent maintaining things.
