Hopefully state/local governments will realize the potential increase in tourist spending that Airbnb makes possible. I paid $X for a week of lodging via Airbnb. The equivalent hotel would have cost easily 3X. So now I've saved 2X... and since I'm on vacation I have no problem just spending 1.5X on purely fun stuff (restaurants etc). Also note that having to pay 3X for a traditional hotel would strongly discourage me from going on vacation all together.
