"Street art is an efficient way to bring “cultural assets to a neighborhood that didn’t have any,” says Curran. But things can go south quite quickly. Authorities prefer to have a Guggenheim Museum instead of a graffiti squat. They are reticent to finance street art, but they change their mind when an artist becomes famous. The situation becomes schizophrenic when there are “laws that punish street art severely,” while at the same time “the cities commission artworks to these artists, museums expose them and galleries sell them,” says Ben Yahklef."
