Earlier quoted context omitted.
I understand the problems of setting a precedent. I don't, actually. If the financial industry has taught us one thing, it's that you can insure anything . Let's assume that this is a very rare occurrence and that the total cost of making this right (say, tops $100k?) can be amortized over the profit being generated. I have a hard time understanding how it'd be rocket surgery to get something in place to handle these…
AirBnb is illegal in some of the states (and when states/hotel industry/cities get a wind of this story, it will probably be illegal in all the states), so I doubt any legitimate insurance companies will be handling this affair.
Also, if it were indeed the case that AirBnb is soon to be illegal, it would make more sense for insurance companies to sign them up: the risk of AirBnb being shut down ought to reduce the likelihood that they'll need to pay out.
