1/ Here’s why I think Ethereum & Proof-of-Stake are bad ideas.
That’s different because in those cases there are exploitable inefficiencies, whereas every hash in PoW goes to secure the ledger. One hash mined == one hash harder to revert.

The work in PoW comes from searching the hash space (mining) not from creating an individual hash. Immutability comes from an honest majority sharing the same history. PoS improves the inefficiency (mining) while achieving a similar result (honest majority with same history).
-
"similar result" is your quite arguable conclusion. The "honest majority" of machine consensus is more provably true than consensus involving corruptible humans.
-
Who said anything about human consensus? In both PoS and PoW the majority of nodes (machines) share the same history (consensus). If they don’t you have orphans or a hard fork. Human consensus has nothing to do with PoS. Another straw man argument...

You are conflating the generation of the history with the history itself. Your claim is basically that the only way to securely get that history is through mining. If that were true every new node would need to re-mine everything.
