The issue is the granularity of regulation in that the details and legality of airbnb is decided not on a national or state level but by the municipal authorities, from a regulation standpoint it's totally unmanageable and unenforceable. Your average airbnb host isn't subject to the same hygiene or safety certifications let alone business and tourism taxes. I cannot imagine there to be a million Airbnb rooms that are compliant with all relevant by-laws. I'm going to go out on a limb here and suggest that the hotel industry has in the past actively fought against normalising the laws that affect them because I bet... They exploit them too.
