As a former airbnb host, I feel these problems are due to existing bad policies on new construction or zoning unless the city has a huge boom in tourism and not enough hotels.

It's a reflection easily corrected though(more hotels).

I've lived in one that did that and watched the demand tank some everytime a new hotel went up. City had removed limits on downtown building a a few years ago....prior to that airbnbs did so good that city told hotels to screw off because they needed them to meet high tourism demand...even legalized them!
