The ideas of Ludwig von Mises, an economist of the Austrian School, have been resurrected by critics of a RBE in an attempt to show that a moneyless economy is impossible. Despite numerous attempts to disprove the criticism, the spectre of von Mises still hangs over the social movements that support a RBE. But my defence here is not merely yet another attempt at disproving von Mises, but emerges also from the frequency of misunderstandings and misuse of his critique, and some issues regarding the proposed solutions from RBE supporters. I wish to set the record straight on what the true challenge of von Mises’s ‘calculation problem’ is, but also offer internal critique against some rebuttals against von Mises by RBE, such as the idea that computation solves the calculation problem.
