You confuse skill with talent. By your logic, only the most photorealistic painters would be great artists.
Talent and skill can definitely co-exist, but they're not the same thing. The problem is that some people, especially on internet forums, either think they're mutually exclusive, or that they are the same. It's impossible to argue with people who think that a piece of music is shit because the musicians play to many notes. People who think a high notes-per-second count is a seal of quality are also idiots. Yeah, it's impressive, but does it work with the music?
The art is in the end result, not in the techniques used to achieve it. Let your ears decide.
