I have yet to see any evidence in regards to your claims about Uber or Airbnb.

Secondly if the prior taxi system is evidence of regulation i think it's a safe assumption to make that regulations helped neither the consumer or the providers. Uber in SF is doing 3-4x what the entire taxi system was doing prior, that's evidence of demand not being met. Artificially restricting supply is never a good idea.

Uber is only doing so well because people prefer their service to the alternatives, people aren't stupid, they can do what is best for themselves.
