Modern Monetary Theory has gained significant influence in academic, policy, and political circles over the past decade amid growing fiscal crises. It claims that currency-sovereign governments face no meaningful fiscal constraint, that deficits are benign instruments of social welfare, and that money creation is a legitimate policy tool. This paper comprehensively refutes these claims. It demonstrates that MMT is not a progressive monetary innovation or a heterodox alternative to mainstream orthodoxy but rather the most sophisticated ideological rationalization for institutionalized monetary fraud yet produced. MMT’s state theory of money is historically false. Its currency sovereignty claims conflate legal impossibility with economic sustainability. Its dismissal of inflation as a manageable policy variable contradicts the dynamics of monetary confidence collapse. And its framework systematically violates the natural-moral law principles of truth, consent, justice, and nonaggression that legitimate monetary systems require. The paper concludes that MMT is fundamentally flawed, structurally violent, and economically destructive. Africonomics offers a principled alternative grounded in truth, sound money, and human dignity. The path to monetary justice, economic stability, and human flourishing runs not through MMT but through its categorical rejection and the adoption of sound monetary systems, such as the Nilar.
