Wrong. The skill can be used to copy. In fact the only way to tell if a painting is real or fake - is to check the age of the canvas and paint. Art doesn't need to come from one's mind. You are digging a deep hole here and you are in it.
And I don't wish to repeat myself in DMs either. To get back to the topic - the game is objectively good irregardless if some people don't like it.
