"If the thought of eliminating money still troubles you, consider this: If a group of people with gold, diamonds and money were stranded on an island that had no resources such as food, clean air and water, their wealth would be irrelevant to their survival. It is only when resources are scarce that money can be used to control their distribution. One could not, for example, sell the air we breathe or water abundantly flowing down from a mountain stream. Although air and water are valuable, in abundance they cannot be sold.
Money is only important in a society when certain resources for survival must be rationed and the people accept money as an exchange medium for the scarce resources. Money is a social convention, an agreement if you will. It is neither a natural resource nor does it represent one. It is not necessary for survival unless we have been conditioned to accept it as such."
