Who determines a Work's Worth

“Who Determines" is the next area we will contemplate.
Art expresses what we believe, in all its diversity and this often perplexes people. The fact we see something exists but wonder why it does, often confuses us. A work’s existence forces us to interact with it and then we try to discover its value.
Since the end of World War 2, thinking about art and its worth devolved to: “art is whatever we say it is.” This answer is un-satisfying and deep down we know Art is more than “whatever we say.” Such viewpoints are hollow and untrue as we continually observe good works and bad works (for more on this point, refer to my post, Evaluating Works).
Observe how a work’s aesthetics has to conform to laws and standards according to the nature of its medium, in all its variations, all the while, being guided by the idea’s character. How successful a maker is at bringing out an idea's character is what we usually discuss.
We do not have to be locked into society’s narrow-minded indoctrinated thinking: where a work’s value and its meaning is not centered on the work.
Confused thinking surrounds the notion that aesthetics is subjective, just an opinion or it is about how it makes us feel. It is assumed if we are to keep societal chaos in check, we must say everything is the same quality. When I acknowledge a work’s worth, either good or bad, it upsets people. Does recognition of value falsify the notion “everything is the same”? Maybe. Assuming everything is alike as a commodity, my work’s execution equals yours, no matter how good or bad it is, especially when it is bad. But not everything is bad and maybe that is the problem with this outlook.
“Who determines the standards?” We are indoctrinated to believe nothing has intrinsic value and someone who is not a work’s maker determines its worth; often someone classified as an “expert”. Therefore asking “who” places the standard seems natural and we will follow whatever the superior powers endorse. Or we assign its worth, based on how it makes us feel. But feelings are poor standards of evaluation, as they are always changing and never can objectively define what is outside its subjectivity. But we can objectively determine what is outside ourself.
Therefore, a work's worth is established by the person who brought an idea out of the ether, shaping and developing it, to becomes something that exist in the real world. Michelangelo's view of sculpture is a way to understand this. He said the sculpturer sees a statue in the marble and takes away the excess material until the envisioned statue is revealed. Only a maker envisions how to bring an idea into reality.
