Bingo, art "market". Buying and selling. Economies and economics. Supply and demand. Marketing, marketing, marketing. Everything you just described, that's business, and art is the product, no different than Ford bringing out a new car. (There are always going to be what the majority of a society would consider artistic outliers, such as a banana taped to a wall, or for the car analogy, the Yugo. Folks like that, claiming to be artists, to me, are not out to give art to the world, they are out for the short-lived shock value. And when they call it art, those who proclaim to be art critics clamor all over it and create publicity- good or bad. And the rest of us unwashed common folk see it and shake our heads with some level of disbelief, and debate amongst ourself whether or not that banana is art.)
Making art for monetary gain should not be a reason to make the art- for me. I make art for the sake of making art to be presented with no expectation, nor acceptance, of like trade, and I am stuck with that notion being art's purest form. I guess if someone wants to then make a dollar on their art, they have two motivators for making it, not one. How many artists give up being artists because they can't feed themselves by way of their art? That's an artist who needs to find another way to earn a living while continuing their art work separately. That person will find all the satisfaction they seek if they respect that notion.
I wonder if all art that is sold could or should be classified as "commercial art"? Someone is in the business (at any level, even the hobby level) of making and selling art; selling is their primary purpose for practicing the craft, to make artistic items with the intent of them being sold and providing an income stream to the artist/crafter. (I did that for a very brief period.) That's a business. I have no problem with the perspective of commercial art, and it keeps the motivation, the reasoning, honest and forthright. It may even help the artist in the end if they embrace the attitude of being an entrepreneur- you want to make art AND make a buck.
Editing the next day- I just re-read the original message in this thread. Paragraph 3 supports my position in that art cannot serve a function or have utility of any kind, say the art scholars. Now, in all fairness, early in this thread I poo-pooed art scholars. That said, they apparently would support my position in that as soon as art is traded for money, that art suddenly has a function, which is to provide money to the artist (or to whomever in its chain of ownership). It no longer exists only for its own aesthetic, therefore it is not art.
