The company was started to help political operative (the most amenable form of interns) to find a dry place to nap during conferences: that sounds like a specific, unaddressed need rather than a tax evasion scheme.
> highly taxed, while most AirBNB rooms are not - apartment rents are often rented at submarket prices under rent-control schemes,
Actually, the handful of people operating ‘hotel-like’ plans (short-term flat-share, really) that you refer too are always doing it from recently build, not rent controlled, purchased flats, for all sort of reasons; they all explicitly mention that operating anything significant from a rent-controlled flat will get you out in the street faster than you can list your flat.
The classic case is this ‘let’s limit the number of license for safety reasons’: if you want high-grade manure, that is top-shelf bullshit. I went to San Francisco once, and I never felt so much in danger than in that cab: no seat belts, speed limits were for the wuss that he was honking at through-out, he gave multi-tasking an Olympic status; even looking at the (packed) road was too much for him. To the point we felt the need to call the company, if anything to make sure whomever would surely die in there soon would have proper insurance. Let’s say we were told in no uncertain terms that we were alive, therefore our livelihood was not supposed to be our concern. Same for rats in hotels: I don't mind an accident, but I expect action, not denial. I don’t understand how limiting the market is going to have a positive impact on service when the human touch is… lacking.
I chose AirBnB because they had interesting features, as in, creative business model that make they offer relevant to XXIst century dweller: personal contact, restaurant recommendations from our host that make sense, a Wifi router that I can physically access when it needs rebooting, free access to kitchen that won’t charge me a day’s worth of wage to toast two slices of bread at night, significant rebate when staying more than a couple of days.
> hotel rooms are highly taxed, while most AirBNB rooms are not
As you point out: they are intermediaries, and I’m positive they wouldn’t care charging extra tax. I would put them on a list, and that list could be artificially limited, making them possible victim of a lobbying effort by hotel chains who want to keep a stronghold on a market, rather than admit it has evolved and adapt -- so I understand their reservations. But passing taxes is generally a business-neutral act, so I doubt they care that much. Once again: look and compare, they are not trying to be cheaper than hotels.
