Money is traditionally thought to have certain properties, which are the features that characterise its social functioning — Store of value, Medium of exchange and Measure of value. While these are usually thought to suffice in describing the social role of money, this text tries to address a function that is under-theorised as the root of its social constituency; Money as a enabler of social coordination in light of complexity scaling. This perspective is informed by an eco-cognitive approach to cooperation. By understanding money as an infrastructure that allows organised groups of individuals to cooperate, as they become depersonalised, usually through increasing the number of individuals and their spatial organisation. If we are to understand that the ends of a monetary system is to enable social organisation to scale in physical dimensions, then we can imagine different systems for doing so. This is not be understood however, as a return to Hayek, is not so much that information is an important vector for the understanding of markets, but that the encoding of information at a scale is the very reason for markets to exist. This shift in understanding is a necessary step in contesting the premises and conclusions of this sort of thinking regarding the optimal states of equilibrium that markets understood as systems for the encoding of information can reach. This text is then divided broadly in two parts, the first gives an account of the relationship between cooperation as an historical necessity in human settlements, and money as the necessary infrastructure for allowing these settlements to scale in size. The second part departs from these ideas and imagines ways of instantiating different systems, which should not be based on artificial scarcity, as a means of organising society and the necessary complexity to maintain it.
