This is how I interpret your post. Correct me if I have it wrong.
As I understand it what you’re saying is that supply of art is undermined by interference in the demand. This suggests the world of artists and production of art is being perverted by someone or something, and that the work produced is not the work people want. You also seem to suggest that the consumption of art should be at a higher level, that people would buy more art if they could relate to it.
This then means the art produced should be consumer driven, then it will be ‘real’ artwork.
If that happens then it becomes a commodity. But I think we already have that with the books, films and music available today.
First of all, I don’t think the world needs more art. But it always needs good art. The thousands of best seller books (airport lounge) compared to what we regard as literature, is not art, and neither are all the works turned out in the same way in music or the visual arts. That’s just commerce. There’s nothing wrong with that, it serves a market, and its popularity and production costs make it affordable for the people who want that.
The number of great works of every era are very slim. The nature of the work itself means that the artist can only produce so much if it, and even then its quality varies from work to work.
I don’t think great work needs money to come into being. Writers produce their work before they know if it will be picked up by a publisher, (Though for some time writers have received big advances to create that work.), visual artists prepare their work before a gallery accepts it (again, except for those who have a following. So this is virtually commerce). Artists, being what they are, are compelled to produce work regardless of the future.
So I can’t see how creating a demand for art necessarily leads to good art being produced. If you purposely work this out by demand then it’s a commercial transaction and we already have that. Nor can you create a demand for good work, because one of the qualities of good work is its originality, which can’t be anticipated.
