Great idea/ideal, and I share it... but until I'm wearing a HUD that can tell me what materials and processes in which factories and ports were used at each step of production and distribution contributing to each lot of cereal in the store, I'm not really informed enough at the point of economic decision to accurately reflect my utility function through my purchases. And good luck getting the producers of goods to share details even approaching that. As a class, they routinely fight additional labeling of their products, getting access to their production and distribution databases will be a far worse fight.
