> Crypto is a needed option, it can be made to be more environmentally friendly. I personally often do not (and cannot) benefit from the global banking system despite all the waste it produce from electricity to wasted manpower to the carbon footprint of material for buildings and offices.
I'm choosing to ignore the parts about buildings because the appropriate comparison is with electronic payments. A transition from in-person banking to Bitcoin is less likely and more costly than a continued transition from in-person banking to purely online electronic banking (not that I think it'll be desirable to anywhere near 100% complete such a transition in my lifetime).
So doing an apples-to-apples comparison, even assuming crypto ever actually becomes meaningfully more environmentally friendly, how does crypto replacing the current global banking system lead to a less wasteful system, measured in environmental terms? I see no way it can.
I also think:
> There are no alternatives that are as good as [the current system], on pretty much any axis. This includes all crypto.
Crypto has far more issues beyond environmental ones, and the very real issues with the current system are not meaningfully helped by crypto. The issues are political problems without much in the way of a technological solution, except at the margins. If crypto wants to stay relevant there, at the margins, that's mostly fine by me.
