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.

There is only one way to ensure that a company will make decisions in the interests of the people it serves: Put those people in control of the company. So let me introduce the T corporation. Most business-savvy people know that there are S corporations (Subchapter S of the Internal Revenue Code) and C corporations (Subchapter C), but almost no one thinks about forming a T corporation (Subchapter T). But T corporations have been around for a long time, and they have a major benefit of not paying tax if 1) they are governed democratically by the shareholders (i.e., everyone gets one vote in the election of the board, regardless of share value) and 2) the earnings of the company are distributed to the shareholders on the basis of how much they patronize (i.e. do business with) the company.
