That being said, it's not that easy to just blame the public officials for all the chaos. It is a reasonable danger to these services, there are so many unknowns. The reason why the cab business is regulated in the first place was for public safety, so that cab drivers wouldn't just ask for exorbitant prices, take your luggage hostage etc. Remember, you are still just jumping into a stranger's car. Regulation was introduced to remedy these concerns (I'm not saying they are effective)
Airbnb shows how regulation is a reasonable concern. Once you go beyond the early adopters, there are so many things you have to deal with like insurance, liability, cleanliness etc. We can't just expect the world to change in an instant and naively believe everyone in the world does good.
