On the surface you can't assume either way if a listing on Airbnb means the unit is permanently off the market or not, likewise with counting or not counting every blocked-off calendar date: if it's not a period of 4-8-12 months blocked off, then it's likely not being rented to a long-term renter; the lister perhaps even perhaps booked those block-off calendar dates through a different service, or did the transaction not through/off of Airbnb. Whether it's $100MM or $616M - it's a sign that there are external costs that that city and society must shoulder because of the higher prices people can charge with shorter-term rentals, primarily to non-locals who may or may not be staying or moving to the city.
