Etherium and virtually the whole rest of the crypto scene that is “not bitcoin” has pretty soundly rejected the wasteful Bitcoin design. There was even a fork of Bitcoin that would have used the much more efficient proof-of-stake, but since that would be bad for everyone with a proof-of-work “mining” rig it didn’t take over.
It turns out there is just zero real world need for an untrusted distributed ledger
An “untrusted distributed ledger” is literally the backbone of modern software development. While you could plausibly split hairs and assert that git requires “trust”, I don’t think you’d wind up in a spot that both supports your assertion and a cognizable difference for anyone but mathematicians and security nerds. (And even if you did, the exact same sort of non-scam usages of blockchains are ones that operate like git, with the ledger used for something else.)
Two points:
