> One you remove the need for PoW they are barely any more inefficient than a master-master DB with the combination of immutability and known entry ordering.

Once you remove the PoW - it's no longer a blockchain. That is what a blockchain is. If you believe that blockchain's don't require PoW - then off the bat you have major security problems. But in addition to that - your definition of blockchains would mean that we've been using blockchains since the 80's

So you don't consider PoS systems blockchains?

PoW literally has nothing to do with what the blockchain is only in deciding who can add the next block and there are a lot of ways to do that when you know all the participants.
