My point was that even if you drive costs to 1000x, you're not somehow magically going to reduce consumption. Human output will match those efficiency gains in other forms. Imagine things like synthetic diamond jewelry being the norm, thermal pyrolysis of methane and CO2 into plain carbon, mining deeper underground for precious minerals, etc. A person in the 1890s could not have envisioned the things that would happen just 30 years later, enabled by cheap electricity.
