Mr. Schneiderman has targeted Airbnb, an online service that lets users easily rent homes or apartments for short-term stays, giving travelers a new option. The hotel industry, concerned about being disrupted, is lobbying hard to kill the upstart. Mr. Schneiderman went to court demanding the names of people who rent out their homes to see if they violate any laws. Airbnb objects to this fishing expedition. With a valuation in the billions, the Silicon Valley company can afford lawyers to protect its customers, but costly regulatory overreach will inevitably suppress new startups from trying to compete.

Like Airbnb, mobile-phone app Uber creates a marketplace directly linking buyers and sellers—in its case, passengers and drivers—outside the ornate regulations of analog-era municipal taxi commissions. Brussels, Seattle and Miami have banned or strictly limited Uber cars. New York’s Mr. Schneiderman objects to the company’s practice of pricing more when demand is heavy. The alternative is severely restricted supply, as anyone knows who has tried to hail a cab in the rain.

The drone industry in the U.S. has been grounded because the Federal Aviation Administration has banned commercial use of drones pending new regulations. Meanwhile, countries such as Canada and Australia encourage drones. “As American regulators struggle to come up with a rulebook for the fast-moving industry,” Toronto’s Globe and Mail bragged recently, “Canada has emerged as perhaps the center of commercial drone technology—from Ontario farmlands to Alberta’s oil sands.”

Other examples include the Food and Drug Administration’s scrutiny of 23andMe’s marketing, which forced the company to stop offering health data from its at-home $99 genetics-analysis kit, and prohibitions against selling self-driving cars, which have left the U.S. in the dust behind less regulated Europe.
