It does. I am trading off decentralization, privacy, security, ... with (for Bitcoin) more than how much energy I would use in a year and CO2 I would use in a life, per transaction.

They do offer a comparable product, and you need to compare their upsides and downsides.

Not really. It is a tradeoff but you can't really compare their efficiency because they don't provide the same features. Credit cards provide none of the properties provided by cryptocurrencies.

You're looking at the cost of transactions. You're not looking at the cost of private anonymous trustless decentralized uncensorable unsanctionable irreversible transactions.

I think bitcoin is a waste of resources because it failed as a cryptocurrency. I wouldn't mind even larger amounts of resources being poured into better coins like XMR though. I don't care how much energy it requires, those properties are just too valuable.
