Because much of AirBnB's business is flat out illegal due to zoning, property laws, HoAs and leases, I think requiring them to provide a better system for accepting accountability for the negative externalities they create is reasonable.

That's not at all what I'm suggesting. I'm suggesting an easy way for landlords and others to determine if a property they own or one near them is being listed on AirBnB. After that there are a ton of avenues for justice one could take, and it would probably include, along with government/HoA response, a procedure for forcing AirBnB to take down the listing given proof of ownership or something, similar to DMCA, but this is not an unsolvable problem by any means. It's one AirBnB is choosing not to solve because it would destroy their business.
