Not really. I am saying consider that energy usage for traditional banking is also high. If you compare numbers then I believe it needs to be global or pro rata.

> It supports fewer transactions per second

I don't think this is a relevant comparison to be honest. The high energy usage of Bitcoin is not to handle transaction volume, but to secure the network and funds.

Payment cards is a secondary payment layer on top of the banking settlements. Bitcoin is more equivalent to bank settlements.

Second layer solutions for Bitcoin such as Bitcoin Lightning and crypto payment cards (Crypto.com, Coinbase etc) are more comparative to bank settled payment cards and can (and does) provide much higher transaction volumes for Bitcoin. Which also means that payment card energy usage should not be included in any comparison if done (imho).

Just as a side-note, Christmas lights in US used more energy than Bitcoin miners (at least a couple of years ago) and for sure more than a lot of countries. Bitcoin provides sound money for unbanked people all over the world. What would you rather have?

LOL, no, it does not. It does nothing at all for the unbanked.
