When graffiti culture was still in its infancy, most of the people who took it up were not involved in any kind of anti-authority struggle. There are some people who express the oversimplified opinion that it was simply an explosion of imagination whose spread resulted in billboards, alleys, subways, and more becoming public canvases, yet I would contend that the roots of the phenomenon known as graffiti are inextricably linked with the more primordial aspects of humans. Graffiti is treated as a social problem affecting the whole city and denounced as vandalism, but if we conduct a thought experiment into the origins of graffiti, we can expand discussions into the territory of visual art theory, aesthetics, cultural anthropology, and sociology. Simply regarding it as the act of defacing objects is too narrow-minded, which is why it is valuable to conduct such a thought experiment. Today, just as in the past, the acts of graffiti by people expressing themselves by assuming alter-egos and with competing styles share some kind of essence that extends to the year 2021.
