We are talking of two different things here, traffic versus access bandwidth.
It will be a while before the average household generates 5 megabit/s traffic.
Even in Korea and Hong Kong, where the average broadband link is in the
5-10 Mbps range, average traffic is about 0.1 Mbps.  The main purpose of
high speed links is to get low transaction latency (as in "I want that Web
page on my screen NOW," or "I want that song for transfer to my portable
device NOW"), so utilizations are low.
