It is newsworthy/noteworthy that reduced competition leads to higher prices?
From what I understand, cities like NYC have very carefully-crafted laws regarding hotels designed to protect the rights and safety of both the hotelier and the guest. AirBnB wants to be exempt from all those regulations and hospitality taxes because, well, it allows them to offer a lower-cost option without any significant investment. In effect, AirBnB wants to be a hotelier that owns no hotel rooms, pays no hospitality taxes, and has no legal responsibility for anything that happens in a space they rented.
That AirBnB can't pick and choose the tax, safety, and other regulations that apply to their 'service' isn't discriminatory against AirBnB, it is treating everyone equally.
