Indeed - why should you have to be able to watch a film instantly all of a sudden, just because, on a whim, you've suddenly decided you would like to?
What a peculiar question. You may as well say why should we be able to pick up the phone and speak to a relative who lives at the other side of the planet, or why should we be able to flick a switch and a light come on, or why should we have broadband internet...and so on. The answer is "Why shouldn't we?"
As for bandwidth and our infrastructure not being up to it, in most cases I'd be more than happy with the quality provided by iPlayer and YouTube. They also seem to be able to make it pay.
All it needs needs is one rental-firm to go at it in a big way and crack the market, then they'll all be at it. It will happen.
