Producers must somehow more than pay for sequesters to sequest. The technical details confound me right now. Imagine if every CO2 molecule were somehow unique:

Producers must somehow more than pay for sequesters to sequest. The technical details confound me right now. Imagine if every CO2 molecule were somehow unique: carrying with it a physical hash that could cheaply identify the processes that produced it. In this scenario, such an economy would become feasible. To reduce complexity and cost, it needn't be every molecule. Say just one in a quadrillion, at an exactly fixed rate. Of course CO2 is actually generic, as far as I know. Yet with only one wave of the magic wand, an economic solution has appeared. Assuming regulatory and societal support, which should be forthcoming in this current climate (pun intended).
