Why is no one pissed about the amount of energy our FIAT banking system uses?

Crypto gets a lot of criticism for the amount of energy it uses, but why is no one comparing it to the amount we use for our current FIAT system? Clearly it's harder to estimate because banks aren't openly sharing the data on their servers, but I would think the environmental impact of financial institutions must outweigh crypto. Plus crypto is in a position to adopt new methods like proof-of-history and implement AI in ways that will make it much safer and cost-effective...

While I'm really concerned about the environment and I understand that there's currently a big impact by crypto, shouldn't we instead be focus on implementing decentralized approaches for global trade and commerce which could actually help the environment? The potential for social change is so great (and society is the real problem), I don't understand how people can just dismiss it as anti-environmentalist. I think people should be asking what we can get out against what we put in.

Am I wrong or is it that the tech is just so new that no one actually understands it yet so they're just acting impulsively out of fear of the unknown?
