Markets are manmade concepts derived from marketplaces as its cause, temporal consequences derived from the current exchange of participants in a marketplace.
The existence of a marketplace, as a cause, not necessarily constituting a market (consequence) of buyers willing or able to engage in the future. No inference to a cause, the constitution of a marketplace, can be inferred from the existence of “a market”. Or as we all learned in school, correlation does not infer causation.
With the all-too liberal use of and dependence on markets in classical economics, making it a voodoo science, systemically confounding consequence with cause.
