Charles Hugh Smith questions the whether gold is the best way to store wealth in the coming "Great Transformation", when oil becomes very scarce. (I remember how valuable gasoline was in the movie Mad Max 2: The Road Warrior). He suggests that having a convenient supply of energy and food are the most valuable sources of wealth in very hard times. Excerpts below.
If we understand that "money" as a store of wealth is simply stored energy, then we reach another understanding of "the problem" and thus of the "solution."
Let's say that the fragile supply chain of remaining oil breaks down in a complex interaction of positive feedback loops. Oil would not just be costly; it would be unavailable to individuals. The government would undoubtedly ration what was left for essential services like agriculture, food distribution, police and hospitals, etc.
Let's say we anticipated this and responded not by hoarding gold but by buying a 100 KWhr/day solar power array, productive land in a mild climate, a store of fertilizer and a few electric vehicles to share with our family/community. We own zero gold but we own a power supply, the means to grow food and transportation that does not require petroleum.
Now would we sell these productive assets for gold? At what price, if they were essentially irreplaceable? What would we do with our pile of gold if we can't go anywhere, can't grow food and have no power source?
The holder of gold assumes that all goods can be purchased with a means of exchange holding a tangible value, i.e. gold or an equivalent commodity. But this may not be entirely true. Yes, we will sell some of our power/energy output for gold, but we will not sell our "wealth" i.e. the power plant for gold, which may or may not be able to buy a replacement. As a store of wealth, gold is no match for a productive source of energy.
The reason is "money" as a store of wealth is simply stored energy. From this point of view, fertilizer is stored energy. You may or may not be able to exchange "money" in any form for stored energy, for "wealth" is either stored energy or the capacity to generate energy sustainably. Everything else is merely a means of exchange.
Will gold hold more value as a means of exchange than paper money? If history is any guide, yes—but that's a different "problem" than building or storing wealth.
There are many other examples of "problems" whose solutions may well completely fail to address the structural challenges we face.
