Art isn't amazing because every piece is 1 of 1. Sure, every original artwork is a product that births its very own market, but cost is not what makes art worthy or worthwhile. Don't get me wrong, I'm all about artists monetizing and making careers of their creative expression, but art is valuable because of the experience it provides the artist & the viewer, not because of monetary transactions.
The market is certainly an important avenue for validating solutions, but supply & demand applied to art brings more to mind than mere pricing.
It's the emotional power of making & communicating that makes art powerful. It's creative supply that fulfills an undetected demand laying latent until we're activated.
It's nice to be reminded that the purpose of something can be the experience itself.
