There are still a lot of externalities that people are cutting corners on, even in the suburbs: proper insurance (by not declaring that you're acting as a hotel), tax (by not declaring airbnb income on your income tax), safety regulations (fire extinguishers, smoke alarms, floor plans etc). Not that all these laws make sense for airbnb, but by not respecting them you're "unfairly" undercutting hotels.
