Lets look at physics to redesign an understanding of economics:
Of course we could explore the nature of energy deeper (and probably will!) but lets keep this simple for now. In physics, Energy is defined as the ability to do work.
The principle of conservation of energy is one of the most far-reaching general laws of physics. It states that energy is neither created nor destroyed but can only be transformed from one form to another.
Potential energy, also referred to as stored energy, is the ability of a system to do work. A coiled spring is a good imagery for this energy. Stored energy cells is another. Cash is another.
Kinetic energy is the energy of an object in motion. The expression for kinetic energy can be derived from the definition for work and from kinematic relationships.
Because the total energy of the system always remains constant, the law of conservation of energy is a useful tool for analyzing a situation where energy is changing form. The idea of equal energy exchange is that when we transfer our kinetic energy (life energy) into services or time (massage, child care, performances, etc) or non-tangibles (“goods”) nothing is lost in value. The same is true for a transference into potential energy (stored energy in the form of goods… this is where cash/coin/paper/tab is relevant). There is no exchange market outside of agreement. The value is inherent and quality subjective; all exchanges are consensual and based on equal exchange without the illusion of loss, inflation and deflation, tax, and stagnation/insecurity/scarcity.
Imagine a swinging pendulum. At the top of its rise, all the energy is potential energy due to height above the stationary position. At the bottom of the swing, all the energy has been transformed into kinetic energy of motion. The total energy is the sum of the kinetic and potential energies. It maintains the same value throughout the back and forth motion of a swing.
The conservation of energy is the paradigm-shifting concept when applied to currency of exchange (money, items, services, and a full spectrum of other energetic exchanges that our current models for society do not incorporate). Equal energy transference, the value of the energy stays constant regardless of if it is being represented by art work, pieces of paper as representation of energy IOU or stored energy cells, child care, farming and food exchange, etc.
Once we can agree on these cornerstone concepts, we can build a consensual reality around currency that is not oppressive to the systems it is designed to serve.
