I think this is a misunderstanding, you're referring to the way you can use art within society and the different cultural things we do. I should have been more specific, I think abstract art is truly art for it's own sake, being measured in value by arbitrary interpretations of meaning. Still, some people make art to practice drawing a certain way or increasing their skill. That even is not art for it's own sake, it's art to increase your skill, and is a representation of the way someone likes to practice and is still a cool thing to look at. I'm simply making the argument that complementing someone on their art that a child drew came about because of the arbitrary interpretation of what "valuable art" is in school.
