No because Airbnb bans are basically political bike shedding. Yell at the guys sprinkling oil on the fire because taking on the NIMBY's flooding the region with oil is too difficult.
"Multiple causes" is just mealy-mouthed pussy-footing, there is one big cause and then a bunch of other distractions as the numbers now prove.
You're theory about some NIMBY conspiracy is significantly worse on every metric then your strawman's theory about Airbnb causing the housing crisis. Both are bad, but yours is worse.
Complex problems seldomly have a single cause not a simple solution.
It's not a conspiracy, they aren't meeting in smoke-filled rooms. It's just a systemic problem, a classic tragedy of the commons. An individual neighborhood move to protect an old church is noble and courageous, but do that all across society and you basically have a construction standstill that is difficult to visualize and effectively regulate against. So yes, it is a complex problem, but the cause is singular, and because of its multi-dimensionality, I find these causes to be far more insidious than "profit-bad" problems.
I think the second more prominent cause maybe costs, labor, material, interest rates etc. But Airbnb's are far..farrr down the list so as to be completely irrelevant, as the natural experiment in New York has proven out.
