> There's a certain po-faced affectation that is necessary to be called an artist. Being good isn't good enough; you also need to convincingly ape the norms of a self-appointed cultural elite.
The cultural elite isn't self-appointed. They clawed their way up there the same way as everyone else who has reached some position in some hierarchy. And that includes various hierarchies of artists.
> The disparity in esteem between pop and rock springs to mind. We have an ingrained sense that if a record appeals to 13-year-old girls, then it must on some level be inherently inferior to a record that appeals to middle-aged men, regardless of the actual sophistication of the music in question.
I think the more standard criticism is that some music is made by a committee as a product whereas other music is the result of a group/individual trying to make good music and that, in general, the latter category is better. I don't necessarily accept this argument, but it's different than the one you're proposing.
More generally, I find your attitude perplexing. If you want to think about this subject seriously, then surely there is no objective way to view art. If that's the case, then saying "you can be goofy and make art" is pointless because it's obvious. It's all just people's opinions. "Being goofy" can be art just like anything else.
Where I strongly disagree is where you sneer at "high art" and the "cultural elite". In my opinion, "high art" is art that is appreciated by rich/educated people who have been exposed to different things than less rich/less educated people. "High art" isn't better or worse than "low art". The definition of art is "something from which people derive emotion".
