AirBNB -- in this context -- isn't being disruptive to the hotel industry. They're doing the same thing, but _worse_. Where legal hotels have consumer protections (like definitely not having lead paint and definitely sufficient fire escapes), AirBNB... doesn't. Where hotels (and B&Bs, etc.) follow zoning rules to make sure they're good neighbors, AirBNB... doesn't.
Now, these rules don't work all the time. They probably can be improved. But don't act like they're merely regulatory capture. That's an aspect, but consumer protections are real. AirBNB isn't doing the same thing better, but doing a different thing worse.
