Where's the threshold of badness here, though? Sure, if 75% of residential units are up for short term rental, it's gonna be really hard for the remaining residents to form a strong community. But if it's more like 5%, or even 10%[0], is that really a big detriment to a "strong community"? That just seems like an easy "no" to me.
[0] And I would expect those units to not be evenly distributed around a city; there will probably be higher concentrations in the more touristy spots where this community stuff matters less, and lower concentrations in the more "sleepy" residential areas.
