Out of all of the art that is done I am pretty sure only a portion are a hook for a Kickstarter or marketing material.

Most worthwhile art is done by people who look at life as a different type of quantity. Whether valued higher or lower, the different outlook is really what makes for interesting art.
(You could have chosen a less contentious example of a meritorious practicing artist :-)
On the same note, what may be more contentious is the art of crime. The art of murder. The art of Sherlock Holmes deciphering the creative tendencies behind the craftiest of criminals. Murderers. Thieves.
Are terrorists also artists? That my friend, is contentious.
