Since the earliest times, people have done business. As no man is an island
[1], humans have always needed their fellow humans to obtain all the goods they need to survive. When they needed these goods, it was natural for men to trade with each other. For, often, the surplus that man obtained from a certain activity, hunting, v.g, needed to be traded with other members of the community who had surpluses of other things. It is intuitive that men, from the earliest times, seek an efficient allocation of the resources at their disposal.
