So, this doesn't have to go to ad absurdum to become problematic. We depend on a social contract between people who live together to make things harmonious and not devolve into violence. (E.g. neighbors showing up with guns when a party gets too loud; or abstracting the violence, members of the neighborhood calling the cops on small infractions of the law.) So, that gets back to the problem. AirBnB has not solved the problem because the people who are affected are the neighbors of the AirBnB. If the people renting the apartment are not in the apartment itself, they will give the guests 5 stars if the house is clean at the end. However, the neighbors might give that same guest 1 star because they were partying at 3AM, keeping the neighbors awake. So, we get back to calling in the police and making the place worse for everyone. A hotel has people on the premise to monitor; an AirBnB is not guaranteed this.
