I think my point is that visual outliers are what’s needed to keep the environment stimulating, but unfortunately the only visual content that’s updated with any real frequency are commercial advertising spaces. This is why the ephemeral nature of street art is so essential—because it creates a visual heartbeat in the city by people who are living in it, rather than just marketing to it. But what does the city do with these works? They remove them as quickly as possible and threaten to put the people who make them in jail. - Mark Jenkins
