That might be true but 46.64% of gold demand is for "investment", and a further 8.58% is for "central banks". In other words, most gold produced is hoarded and not used for anything productive. If you're against bitcoin because you think it's a non-productive use of energy, you should also be against investment/central bank use of gold.
Even if hoarded at the moment, energy spent mining the gold was not lost. Gold can be sold tomorrow for its practical uses. Energy powering Bitcoin transactions is gone. (Like the the energy powering bank servers)
