Proximity decreases opportunity costs. We can also argue that as a consequence of reduced opportunity costs we can create opportunities otherwise impossible.
And as a consequence, we compete to discover and homestead those opportunities.
We make this density possibly by the high cost of forgoing opportunities for imposing costs. Thereby preserving cooperation despite an equal decrease in the opportunity for parasitism. As such we exchange the increased cost of forgoing opportunity for parasitism for the decreased costs of opportunity for homesteading opportunities.
This concept is missing from the literature.
We focus too much upon money that provides numerous additional discounts. And we focus too little operationally on the creation of conditions that make trade and money possible.
This oversight is related to the other errors of the enlightenment
