I'm surprised that this argument gets so much traction without any supporting data. It just plays on fear.
First, nothing you listed is an externality but rather direct results of poor behavior. An externality would be something like 'decreases property values of neighboring properties' or 'increased rents due to lower supply'.
Second, what data do you have that proves these scenarios are more likely in an AirBnB than a long term tenant? You're only supporting evidence is inference; if people are going to behave poorly then it makes sense for them to rent an AirBnB away from home. But there's an easy counter argument: pressure from neighbors will keep these incidents to a minimum. Sure, there will always be hosts are not sensitive to neighborhood pressure, but that same logic can be applied to long term tenants who have bedbugs, throw parties with loud music, litter, engage in criminal activity, etc. Simply put, all of negative scenarios you outline can occur with long term or short term tenants, and there is no evidence that these behaviors are more common from short term tenants.
Third, comparing all AirBnB's to skeezy motels is like saying all restaurants are roach-infested mold-filled 50-point scoring health hazards. This is a classic straw man argument. What about Marriot or Hilton? Embassy Suites or DoubleTree? Do they fulfill the reputation of "skeezy/short term motels"? This is an argument for better inspections and code enforcement, not prohibiting AirBnB.
No one expects neighbors to file daily lawsuits, but neighbors can notify the police if there is a noise violation, etc. Once again, there is no difference here between long term and short term rentals. AirBnB requires more identification than any hotel I've stayed at, so this argument actually supports AirBnB as a platform.
Lastly, your bank analogy is frightfully off base. First, a bank's intrinsic motivation for monitoring large transactions is fraud and not criminal activity. Second, banks are compelled by law to monitor and report specific types of activities that are likely to be criminal activity, but this is defined by organizations like the FBI, not the banks themselves. Third, you still have yet to prove, beyond casual inference, that AirBnB promotes criminal activity any more than long term tenancy.
