The importance of relativity could be seen in our fictitious city overburdened with restaurants: If you open a pizza bistro and there’s already twenty-five other pizza places nearby, have you provided relative value? Your pizza might be darn good, but relative value doesn’t exist because more than likely, a few other pizza joints are also darn good. Sand could be worthless or priceless depending on its relativity in the marketplace: Offered in the Sahara, it’s useless. In a valley preparing for a flood? Worthy.
