When we exchange what we need, we use money as a medium instead of trading ‘goods for goods.’ In this context, money acts as a means of exchange. When we exchange what we need, we also build wealth by passing on added value to each other. In other words, money functions as both a medium of exchange and a measure of value, as well as a tool for accumulating wealth. But isn’t this a bit strange? Although exchange value comes from goods and surplus is generated from this exchange value, the object used to measure and accumulate wealth is money, not goods. This is because money alone has the privilege called ‘compulsory circulation power.’ In other words, even if value is created, added value cannot be realized unless it’s exchanged. The ability to enable such exchanges is what we call ‘compulsory circulation power.’ - Joseph’s “just my thoughts”
A big supermarket can do business in the suburbs because of wheels. If someone asked me what is one of the greatest inventions in human history that civilization has ever developed, I would say "wheels." The automobile is also a wheel. Shopping carts are also wheels. Without wheels, how many people would go far and carry heavy loads? Mass distribution is possible because of wheels. To do bulk sales, you have to have a lot of inventory. That means you need a lot of storage space. It also means you need cheap real estate. The trivial circle, the wheel, is the key to solving all these constraints in one shot. - Joseph’s “just my thoughts”
