This is pretty absurd as your hypothesis makes no sense. The drive for revenue is going to override any government demand for oversight. Any government stupid enough to put up this would kill tourism which is the lifeblood of many cities. Money speaks and I don't see any government enacting this anywhere irrespective of AirBnb being there or not.

Now for Airbnb I am taking the reverse and contraion position that they will actually come out this ahead of most hospitality companies. Simple they don't own any assets and have the ability to ratchet down or up depending on the macro-environment. Also let's be honest here is that host will come back as its a another way for them to monetize their assets especially the economic situation right now.
