LA says that street artists violate unfair competition laws

The City of LA is on a warpath against people profiting on street art.  Specifically Christian Gheorghiu, who LA previously sought to enjoin from profiting from his street art.  The City is alleging, in a novel theory, that the sale of art which was popularized through graffiti, even though the art itself is legal, is nonetheless unfair competition, because the artists got their name out using illegal means.
