Could or would each of the 2.1 million registered users of Airbnb come up with about $120 per year to complete the buy-out of a $2.5 billion dollar company in 10 years? Maybe. The number of users is growing rapidly, which would reduce the buy-in cost for each user. And I, for one, would probably encourage everyone I know to buy in, if Airbnb took the revolutionary step of converting to a cooperative.

And they get to the keep all the equity.
