I can see that being the case in many exciting locations, but in busy metro areas like NYC I am quite certain price is a major motivator.

Clarification re: popularity, I think we can agree that AirBnB lives and dies with its inventory. If cities/IRS were to crack down on the legal and tax aspects, inventory would significantly reduce.

One concerted enforcement action, eg enforcing disclosure of all who rent rooms to the IRS, or requiring disclosure of apt. addresses to landlords, and a very large part of the inventory will drop out overnight.
