We do tax lots of other kinds of energy, but you have the dilemma where crypto will use the least taxed, least cost energy anywhere in the world, dump the externalities into the atmosphere, and no one can tax energy everywhere to make them pay to clean it up. That's why you have things like coal fired electrical plants that used to no longer be competitive firing up at full capacity again to mine cryptocurrencies.
Crypto mining can't be curbed by carbon taxes in any energy market like normal electrical consumption.
