While I understand the underlying economic argument, I don't think it captures the whole picture. I'm not sure that hardware sitting idle 90% of the time necessarily means people aren't willing to pay for it because plenty of things we own spend most of their time unused. Think about it: cars are parked for most of their lifetime, a household drill might only get used a few hours a year. Utilization is certainly a factor, but I don't think it's necessarily a good measure of the value of ownership.
