That doesn't take anything away from the knowledge work that happens when you develop software, but the code itself is not the art. The solution is the art.
Perhaps like most popular art, it's more about the story behind it.
Nearly every designer and artist knows that artisan stuff does not bring in the money, but rather commissions for "everyday stuff"; in German there exists the term "Eisdielen-Jobs" [1] ("ice cream parlor jobs") for commissioned, boring, "everyday" design jobs like, as the term implies, creating the design and illustrations for a menu map of an ice cream parlor.

Good code is pretty much the solution with some boilerplate tacked on.
But I'd take them every time over a definition of art being "something for which there is a market". Screw that.
