The core principle articulated is the Quantity Theory of Money, which posits that in the long run, sustained increases in the price level (P) are exclusively driven by proportional increases in the money supply (M), assuming stable velocity (V) and real GDP (Y). This mechanism defines inflation as a monetary phenomenon where changes in nominal variables translate directly into parallel shifts in other nominal values, while neutralizing the purchasing power of currency without affecting real economic output.
