Why do people support systems that keep them and everyone else starving ? Because there is the exclusivity of a morsel crumb of bread *today* as a reward for those who serve the system. Now... why do people support systems that poison all living and food growing environment around them and everyone else ? Because there is the "exclusivity" of morsel crumb of poison-free goods *today* as a reward for those who serve such systems ? "I am too busy to pay attention to politics, economies and ecologics... I am busy doing a *real* job of making advertisement managing for recreational motor vehicles" and so on and so on. To stay in topic: Nutritional value of certain foodstuff of certain batch is constant (unless let to spoil). Beans are a good example. This value does not fluctuate with speculations. Human adult being needs about X value of nutrients per month (or year). This too is constant and does not fluctuate with speculations. For thousands of years, in Asia of old, the unit of Rice that one man needs in one year to live, was the unit of money, called "Koku". It worked fine and practical. It was easy to see how many people could you employ and feed this year, by checking how many Kokus were there in your warehouses. So, amount of beans with known nutritional value can be used as reasonable stabile medium of exchange. (Beansm because Rice farming in paddy methods apparently causes alarming amount of methane emissions to atmosphere, as the weeds are rotted away from competing with rice plants). Same could be said about energy. An average human in certain area or province in this planet, can be calculated to need Y amount of Kwh to survive whole year (or month. Yearly includes seasonal fluctuations). This amount is also relatively constant practical unit of economics. Though this value may fluctuate a bit more with changes in weather patterns and conditions, as well as introduction of more energy efficient techniques to the area... as well as possible infrastructure damages. Perhaps such annual/monthly averages for adult human could be measured for materials (textiles for clothing, concrete and wood for housing, metals and rubber for cart bicycling mobility) and medicines (basic antibiotics, antiseptics, preventive herbs etc... as average). Thus, a more complex chimera of an unit, but potentially practically useful one, could be a modern version of a Koku, that contains Medicine Nutrients Energy Materials, a MNEM-Koku ? Thus, for example following real life economic estimations could be possible to perform: "Our collectively operated farm generates about 10 to 30 MNEM Kokus a year. Since we are 15 farmers, we need to store at least 5 MNEM Kokus per estimated low-yield year we intend to survive. That usually seems to leave us about 5 extra Kokus to trade, and exhange... for different nutrients, goods and services." Thank you for your attention.
