I have less of a problem with Uber than with Airbnb. I do believe that Uber deals with issues of trustworthiness and reliability that taxi regulations were put in place to solve, without many major downsides. I think this is one area where technology makes regulation less necessary. Evaluating taxicab service is fairly easy, and reputation works well. Airbnb is more difficult. Evaluation doesn't replace regulation as easily in this case - I'm unlikely to pay that much attention to, say, fire safety unless I've experienced fire problems in the past. There's also much bigger externalities - for other residents in the same building as an Airbnb let, for example.
