“If time is money, space is also money.”
Interestingly enough, warehouse and storage buildings also cost a monthly rent or a fee per square foot of storage, just like any other enterprise in business. Even land and sustainable development can be worth money, and we exchange our wage, which stores a market value, so that we may gain time and space, and vice versa, that we put into strategic use time and space so that money is gained, as in business, or even created out of thin air, as in finance. Thus, perhaps a new definition of money is needed in the context of economic gain in a particular ecosystem.
Everything in spacetime can potentially be worth money. A single dimension, a line in the form of a road, can be a profitable enterprise. Extend that to a two dimensions, and a rectangular surface is created, in the form of land, which can be converted into a farm, with pastures and livestock. Add a third dimension, height, and buildings sprout from land, and trees shoot up from the ground. A business is born. Integrate a fourth dimension, time, and movement and life is born. The farm is alive, and the workers plowing, managers working on the Internet with customer service. Such a business can be profitable for ten years, which represents the flow of money into and out of this farm over time.

“Complexity cannot be avoided, but it can be managed.”
-S. Barkeshli
Complexity is the largest barrier to entry in a free market. Thus, an effective merchant is not only able to deal with the complexity, she is also able to simplify challenges for consumers. Simpleness in itself is a form of customer service, because simplicity used in a genuine fashion helps people get by.
