Exit through the Gift Shop gave me a lot to think about. Your question deserves an essay-long answer. For now, I'll just say that two statements made at the beginning resonate throughout the rest of the film.
1) Bansky's proclaiming that Guetta is a more interesting documentary-subject than he is, even though Bansky correctly thinks (but doesn't say until later) that he himself is clearly more talented as both street artist and filmmaker. It is important to think of the reasons why in this culture , at this time, the less-talented Guetta is indeed a more important documentary subject than Bansky.
2) Shepard Fairey's comment about the nature of power and how a person acquires it in our culture. How the illusion of power, or a "perceived power" can be turned into a real thing by manipulating the sources of mass communication.
There are other significant issues in the film, including material about the concept of art and what it's good for and how it relates to other aspects of the culture, and how things acquire value in society, the authorship of cultural products,etc.
