Fair market value is based on need. There perhaps is an equation that can determine what is worth what but a hierarchy needs to be established. I will throw out some values:water(sometimes has to be purified), food, fossil fuels, steel, building materials, copper, rare earth metals, science equipment's anti-derivative. The point I'm trying to make is a standard mathematical model based on human LIFE could be created and could be used in peaceful...I'm looking for a word that means embargo on an individual scale. Any experts in any field offering facts will lead us in the direction of the mathematics of "VAlUE", but it's going to be a long road (perhaps someone has achieved this feat. To answer the above response, I'd say, fair use should be at play. Certainly if someone is squandering value, using, say, an iron deposit for a playground, they must be stopped. The how is based on situation. Does there ever become a time resource squatting can warrant force? I'm unsure.
