Any discussion of the nature and role of money in modern economies typically brings out a plethora of confusing or conflicting theories, claims and counter-claims about what money is, what role it plays, what dysfunctions it might be responsible for and how they might be fixed. One common set of claims is that money is a unit if account, a medium of exchange and a store of value. I argue the first property is a trivial one and the last is only true if the money is wholly or in part a real commodity, like a pig or some tobacco.
