The present paper takes it as an indisputable fact that subjective-behavioral thinking leads, for deeper methodological reasons, with inner necessity to inconclusive filibustering about the agents' economic conduct and therefore has to be replaced by something fundamentally different. The key argument runs as follows: (a) the subjective-behavioral approach can not, as a matter of principle, afford a correct profit theory, (b) without a correct profit theory it is impossible to comprehend how the monetary economy works, (c) without this knowledge economic policy proposals are unjustifiable, (d) thinking like an economist may be hazardous to the economy.
