Standard neoclassical definitions of money call it a means of exchange and a store of value. But is this correct?

What has happened here, and elsewhere, is that Mises has strayed off his great stomping ground, praxeology, and into ethics, where he is, Rothbard believes, tragically wrong.

"In order to succeed, human action must comply not only with what are called the laws of nature, but also with specific laws of human action."

Logical positivism holds that theory is irrelevant to the empirical results. It is the other way around; One cannot understand or interpret economic data until one has a working economic theory in place.

Praxeology is the method of economics.

In Human Action, Mises had shown that economic analysis leads directly to laissez faire conclusions. He demonstrated that government intervention entails consequences that are unwanted even from the point of view of the champions of these interventions.

Environmental economics is steeped in standard neoclassical theories of efficiency and Pigouvian welfare economics. That's a problem. 

Utilitarianism assumes that morality—the good—is purely subjective to each individual. It also assumes that these subjective desires can be added, subtracted, and weighed across the various individuals in society.
