We are stretching the (possibly false) analogy that Sam is an individual and that Marvin is also an individual. In reality, US Sam is an evolving (or revolving) representative electorate of a lands citizens, and 'Sam' controls the town, land, infrastructure and laws which support the marketplace, including the land, towns infrastructure and laws of the buyers. Sam doesn't need to be an associate, as he owns and operates the ecosystem that makes the market exist, except for the vendors and their tents.
