It's akin to having a group of people sketching on a large piece of paper, trying to build on each other's marks to create an accurate representation of a scene, and someone comes in a scribbles all over it saying "but I see scribbles! All pencil marks are valid! Don't be so limited!".

He/She's allowed to have such an opinion, but this discussion is trying for a particular feel and that isn't contributing helpfully to it.
