It isn't really crypto specific. It is energy producing utility economics. If we had a price on carbon it would effect this equilibrium everywhere. If you accept that we have to change, and sooner rather than later due to inevitability - see Elon's turd in a punchbowl reference, and you accept we aren't going to curtail the things that we find useful that cost us energy, then a price on carbon would bring this about much quicker than without it and is really the only sensible option. Compared with the status quo, burn more dirty fuel faster and cheaply to prevent the economics of green tech coming online, and then, hoping we can innovate our way out of the shitty punchbowl.
