In the future (where all fuel is manufactured by energy from renewables), the price of carbon fuel would simply be the price of manufacture: capturing CO2 and energizing it into fuel. Or are we celebratinng the fact that some people learned about objective energetic cost today? Capturing CO2 has never been hard, and to make the analogy with the loggers planting trees more complete, the price component due to capture would be almost nothing compared to the price component of turning CO2 into fuel which would make up the majority of the price of this future fuel.
