There is no consumer protection there. No method to deal with contracts that are already mistaken. Moreover, the best way I can think of to deal with mistakes in a smart-contract is escrow in something like a 2 out of 3 multi-signature wallet. This essentially elevates the third-party handling escrow to an arbiter. It seems like the kind of thing we'd want to be run by actual courts. Yet, having smart-contracts with build in ability of courts to revert seems to defeat most of the purpose.
