Austrian economics helps us by addressing unrealistic assumptions and preventing further mistakes based on unreal presuppositions. When people’s actions are taken as the starting point, Austrian economics analyses of those actions are revealed to be obviously true. Below, I largely follow the pattern in which Murray Rothbard systematically presented Austrian economics in Man, Economy, and State and Power and Market. I list specific economically-consequential human actions, and I pair each with quotes from the associated Austrian economics understanding. Regarding money, Mises wrote,Money is a medium of exchange.
