Someone has to pay for Lucus Oil Stadium.
If you want to complain that room taxes are too high because governments have overinflated the actual costs of bearing hotel traffic (whether in the vehicular or commercial sense, or in fact both) then I'm open to the debate, but there is a real financial cost to supporting that business which differs from that of a normal rental market.
What I am insinuating is that to pay for Lucus Oil Stadium, Marion county (Indianapolis) and all surrounding counties have increased taxes to any restaurant or bar and a tax on hotel rooms. Rather than lose some revenue on the room tax the government will make a law that charges the same tax on AirBnB rentals. Then they will not lose revenue and this is all about revenue...not noise.
