> With a blockchain, you simply go back, "fork", apply a fixed transaction, and replay all the rest.
You're handwaving away a LOT of complexity there. How are users supposed to trust that you only fixed the transaction at the point of fork, and didn't alter the other transactions in the replay?
My comment was made in a particular context. If you can go back, it's likely a centralized blockchain, and users are pretty much dependent on trusting you to run it fairly anyway.
With a proper distributed blockchain, forks survive only when there is enough trust between participating parties. And you avoid "editing" past transactions, bit instead add "corrective" transactions on top.
