I have no problem with 'agential states' at a coarse level being multiply realiable at the fine-grained physical level, but I don't think you have proved what you claim above. You have only clouded that issue with eventual reference to immeasurable effects of MWI. Talk of identical agential states is unfounded as far as I can see since there seems to be some reliance on physical non-identity to make the difference at the agential level and frequent reference to a catch-all 'coarse-grained'. If the fine grain makes a difference to the agent then you can't claim the agent was 'identical' to some other agent that behaved differently. Identical agential states are surely only identical is the agent behaves identically. Otherwise you can only mean the states are similar or approximately equivalent. You can say the spreadsheet is identical at a high level and different at a low level only if the spreadsheet produces EXACTLY the same results in every relevant respect.
I don't think you are anywhere close to proving anything about free will.
