I disagree. A piece of art is a concrete type of good brought about through human labor for a specific purpose (hence 'art' being a functional definition, although how we define its function is up for debate; e.g. emotional and/or broader intellectual stimulation which includes the common 'art is supposed to be beautiful' view, prosocial impact as upheld by those who believe that art is supposed to have a didactic or broadly moralist function or what have you). It exists as such regardless of whether there's someone to acknowledge its character or to ascertain its quality, just as a watch is a watch regardless of acknowledgement (or awareness, someone not knowing what a watch is doesn't make the object any less of a watch if it comes into his possession; and on the opposite end, someone stumbling upon a natural object and mistaking it for art due to its appearance like in the case of some rock whose outward intricacy and symmetry came about through happenstance and natural erosion does not make it art).
I want to give you a little advice. The purpose of parentheses is to to make a small clarification in case the original thought isn't clear enough, or a little off-topic remark. In a well-written text, the parentheses and their content can be removed, and the text wouldn't suffer from it. While reading, I usually skip over parentheses and their content. But you're not using them right. You can't have 70% of your post inside parentheses. To unlearn this bad habit, I'd recommend to stop using them altogether for a while. It'll force you to increase the readability and clarity of your texts.
(but can be influenced by it, such as by the artist intentionally picking an inferior theme or message in order to appeal to a potential customer base or by underutilizing his skills in producing said good which lessens its artistry for the purposes of greater profits for the amount of labor and resources involved).
You assume that something "less" artistic would sell better. It's the opposite. It's the art that is sought after the most.
When crafting a piece of art, an artist employs a combination of technical skill, original ideas, experience, knowledge, and effort. While all these elements are essential, they are not sufficient by themselves. Art truly becomes art when an intangible element emerges. For a creation to come alive, a miraculous transformation must occur, as illustrated in the legend of Pygmalion and his animated creation, Galatea. Cézanne also attempted to convey this concept when he mentioned that the most challenging aspect of a painting is capturing "a small feeling." This "little sensation" is the very essence of the artwork's soul. The soul is what elevates a piece beyond the sum of the artist's investment. If a painting fails to come alive or Galatea doesn't speak, the artist's efforts have been futile, and the work falls short of being art.
It sounds like you want to say that Marvel's Spider-Man could've been a work of art, if only it wasn't directed at the masses or had a better theme, somehow? Spider-Man doesn't have a foundation to be anything, but an entertainment product.
You don't dumb-down art for it to sell more. You dumb down entertainment products. Art is nowhere near.
And everyone tries to make art. They just can't.

A funny meme is not a funny meme when there is no conscious thought in the entire universe to decipher its meaning. It exists only within the context of human thought.
Art is an encrypted message, and the decryption key is the human mind. If you encrypt a message and throw away the key, and it's physically impossible to extract the message, then there is no message anymore, it's been destroyed.
