There are two primary approaches to creating something: bottom-up design and top-down design . Top-down design is often seen in architecture. People do not build bricks randomly; instead, they follow the design drawings created by the architect. This method executes a plan that has already been established. When asked why something is built in a certain way, the answer is usually that the blueprint dictates its design. Conversely, bottom-up design does not start with a fixed goal, but rather involves setting and implementing small, actionable rules. For example, termite nests follow this approach. Small termites have a simple rule: to pile up soil. They do this without knowing the reason, but over time, the finished structure is remarkable and sophisticated. The appearance of the Sagrada Familia church , designed by Antoni Gaudà and still under construction, closely resembles a termite nest, differing only in size.

In reality, the market value of payment methods is determined by the scope of use, trading objects, and exchange period. This is why money is also regarded as one of the goods. In accounting, the value base is CASH . This distinction arises because cash ( fiat currency ) holds the highest value in use within a country, owing to its compulsory circulation power . - Joseph’s “just my thoughts”
