Therefore, whatever you do that involves money taints you as an individual from the chain reaction regardless of your reasons, morals or political correctness.
What a preposterous statement! The technology of money is nothing more or less than a record of surplus wealth. Since the technology of agriculture was invented, the Paleolithic Era ended, and the first food surplus came into existence, every human being is capable of producing more than he needs to satsify his basic requirements for food, housing and security. (Assuming he isn't the victim of a despotic government that uses force and intimidation to prevent its subjects from acquiring surplus wealth.) Some choose to produce more, others are happy at a level closer to the minimum.
In a complex civilization each of us has only the aptitude, training and resources to perform limited types of work, so we each have to produce what we can produce, and trade with others for the things that they produce. We can't satisfy all of our own wants and needs. Nobody can produce everything!
In many cases we are only part of the production process, and we ourselves do not produce anything tangible, so we have to keep track of how much work we do to contribute to the end product; you may only want to work three days a week and be happy with what that provides for you, whereas I'm happy to work six and am delighted to have a little more comfort, variety, fun and culture in my life. In any case, if I make shoes but need furniture, you make furniture but need wagon wheels, Joe makes wagon wheels but needs beer, Tom makes beer but wants to go to a concert, and Sally plays the guitar but needs shoes, keeping track of these transactions is enormously complicated. Without precise record-keeping, anyone could deliberately or unknowingly end up receiving something that is the result of much more work, or much less work, than he put into the thing he gave out. This is why the concepts of "buying" and "selling" came into existence. This gets even more complicated if Sally needs shoes now because it's winter, and Tom can only make beer in the summer when the herbs he needs are available. In this case the debts and obligations must be
remembered for a significant time period. Multiply this by the population of a whole city, and you've got chaos, as well as both unintended and nefarious inequities in production and consumption.
Money is simply a way of keeping records so that people are fair with one another, since we all have different needs, desires, abilities, and willingness to work. This is why it is always commerce in which the technology of writing is invented, rather than government, religion or literature. Writing always evolves from business records.
