I still think that is a subjective take. Who defines "lazy" and since when can art not be lazy? Should the process by which art was created have any bearing on how the final expressed form is experienced?
The banana duct-taped to the wall could be considered "art by a lazy person", yet at the same time, it was actually a very authentic expression (in this case, an expression that was more along the lines of satire). The "artist" was having an internal experience that he chose to express as a banana on the wall with a piece of duct tape. The artistic expression was a social statement, a joke, a protest. And that's ok.
