If the laws of physics imply the existence of the multiverse, and if the multiverse implies the existence of explanatory knowledge (i.e., humans), then praxeology per se does not necessarily have to be refutable.
Put differently, David Deutsch’s elaboration of epistemology, the Turing principle, the theory of evolution, and the multiverse cements the arguments of Ludwig von Mises and Murray Rothbard—i.e., these theories precede praxeology and hence economics.
Constructor theory defines knowledge as independent of people to account for the phenomenon of life and genes. Praxeology is concerned with knowledge implied in human action.
