These issues are exactly what people refer to as "first world problems." On the one hand, we want everything regulated just so in order to have a nice, well-engineered society with minimal risk and clean consciences when we buy food from another person. Then, whole swaths of affluent folks catch a craving for some good basic (or perhaps attractively quirky) street food and are shocked, shocked(!) when that kind of business is a tough thing to run in this environment.
