I'm really torn about what you are are stating in your story. Having been able to rent an AirBnB on short notice when my mother was dying helped me enormously to get through my grief. The host was absolutely wonderful. The apartment provided gave me comfort in time of my personal crisis. Had I stayed in a hotel or motel, I would have been devastated.
On the other hand, I agree with you that AirBnB's tentacles have reached deeply into communities and titillated real-estate owners to succumb to some get-rich-quick schemes which are ecologically not sustainable.
However, why does a town council allow that? Why are town council people not clamping down harder on these abusers of communities? Why are they not setting up tougher rules on trash ordinances, noise levels, even possibly imposing a visitor fee tax, to make it harder for visitors to abuse AirBnBs in the first place?
If we always place blame on the abuser without declaring our own boundaries with resolution and determination, there is no winning in this game. And I tell you why. It is people in our own communities who always cave in to make a fast buck.
Therefore, to preserve our communities, as you state in your list of what-to-do, understanding what community is is the first step. AirBnB needs to be put in its place by tougher regulations that also hit AirBnB's users harder. They will have to think twice before renting with AirBnB.
