The usual term for this is "regulatory arbitrage."<p>I do want to take exception to one point though:<p>> Of course regulations that truly protect the public interest are necessary. But many regulations are created by incumbents to protect their market position. To try new things, entrepreneurs need to find a back door. And when they succeed, it will all look obvious in retrospect. Today’s regulatory hack is tomorrow’s mainstream industry.<p>It's really a lot more complex than this. A lot of the regulations that seem obviously protectionist now really weren't at the time they were implemented.<p>The FCC is rife with examples of seemingly protectionist regulations because one of the core parts of its mission is to ensure universal coverage. It exists to ensure that every little town in the US gets access to the new communications technologies within a reasonable time.<p>Things like local monopolies/duopolies are the tool that the FCC uses to get companies to serve areas that the free market would leave unserved. The FCC says: "okay, you get a duopoly in Chicago, but you have to build out service to Belleville, IL."<p>The taxi regulations operate much in the same way. If taxi companies were left to their own devices, they just wouldn't operate in the sketchier parts of town. They'd refuse to drive you to the Bronx. Protectionist regulations are the concession that municipalities give to taxi companies in return for forcing them to provide certain services and maintain certain rates.<p>You'll also see a lot of this in the utility industry. Local monopolies with guaranteed rates of return are an incentive municipalities use to get companies to provide power/water/gas to everyone, instead of just the places where it's profitable.<p>Municipal regulation is a very complex topic, both legally and in terms of economic theory. You can't consider the regulations standing alone, when you're talking about industries that in some way form the infrastructure of the city or relate to urban planning. You have to consider them in the context of being alternatives to the cities building out certain infrastructure themselves as part of their mandate to provide service to each one of their citizens.
