Roll back further in history though and the notion of "owning things" was an invention - it wasn't that people wanted to "own a horse" - it's that the entire notion of ownership was invented to determine who got to "ride a horse when they wanted it".

For me, I don't want "to own a house with a lawn". I want "a convenient piece of grass to throw a football around, sit outside and eat lunch, and walk my dog". I don't want "to own a car" - rather, I want "A few times a month, access to a vehicle within a few blocks of my apartment for a few hours".

I think we're saying the same thing here, but the "sharing economy", is, more than anything else, about using communication technology to create finer grained matching between supply and demand - about matching access to goods with people who want to use them, about providing an opportunity to turn time into money and money into time to the extent that one needs and desires.
