Yes, hotel owners and taxi drivers are not exactly pleased about the disruption. And, yes, they have lobbyists to further their causes. But don't think for one second that these people wanted the regulation to begin with. Absolutely not. The regulators wanted to protect the public and put in zoning, licensing, etc. The initial regulation had very little, if anything, to do with turn-of-the-century lobbyists.
For the most part it seems these new companies are facing not some nuanced part of the law, but like basic, prehistoric regulation that is practically universal in the Western world, designed to protect people from surpassingly likely horrible practices--like getting kidnapped by an unlicensed driver. Something not that unimaginable -- at least according to London public service posters everywhere. Some laws have very murky reasoning, I'll give you that. But zoning and licensing in these cases do not. So to say that Cities are stifling innovation by enforcing some of the most basic laws of the modern state, then it's a bit glib.
Incumbents are mad because they are following the rules and some of these new firms are clearly not. But the incumbents aren't the biggest problem, which the article more or less hints as the culprit. No, the problem for 'innovation' is convincing people why they should let the other half of their duplex run a youth hostel without a license. And no, saying your K-nearest neighbor algorithm's got it covered is not going to be enough.
Some might compare this to copyright. And this is where they'd be right. It's not very obvious who copyright protects. No one has ever had a GB of songs cause them to wonder whether their neighborhood is safe anymore. You might even make the same case for fin services. Why regulate those? Well, I'd grant you there too. How many people died from the fin crisis again? Perhaps we are pushing it. Either way, in the land of the physical universe, the universe where Uber and Airbnb are so clearly inhabiting, the reasoning behind the laws is remarkably obvious.
