There is an industry that requires permits to operate. It has hours where it isn't allowed to operate. It is even sometimes zoned into areas it is allowed to operate and areas it is not allowed to operate. The businesses are required to at least not harm the area within which they operate. Ideally they add to the area. These people are street peddlers. They have operated for centuries. Typically being single person operations, they have never had the power of wealth or prestige. Because of this, they have had to bend to the legitimate (and often illegitimate) whims of public pressure.
Through technology, a new commons has developed. Television and radio are the new commons. The Internet is as well, but I won't be discussing it specifically. More people gather in front of their radios and televisions than gather at large public spaces like zoos. Yet television and radio have managed to largely escape the regulatory burdens that apply to other players in the public square. There are of course historical reasons. The first reason is that the infrastructure was fairly expensive. Transmitters and receivers were almost entirely and have almost always been purchased privately. The greater concern was ensuring the system was built. At this point though, the costs of the system are almost entirely sunk.
