You wouldn't rollback HF23, you would restart the chain running Steem 22.X and use that as a starting point. The blockchain isn't being roll-backed, it would be resumed at the point where the alternative chain HF23 is split off. That's how forks work in Proof-of-Stake blockchains. If you consider Steem 23 as the official chain based off of consensus than you are admitting that Proof-of-Stake chains are terribly weak at securing people's money. If we have to "obey" consensus like folks like yourself seem so interested in doing, then sure, the Steem "community" agreed to "steal" from the particular subset of forks that had their tokens moved from their accounts.
