I personally know property owners, large and small, and their properties are fluidly exchangeable between long and short term rentals.
Reducing the production of new rental units will have the obvious result.
I'm not even suggesting that cities should ban or restrict Airbnb, just that doing so can be rational and business owners need to take the risk of this into account. Given the delta in profitability, the market does understand this.
I did not claim that Airbnb units aren't fungible with rentals, that's obviously true, and rereading this discussion I don't understand how you believe I made that argument.
