Well, if the copper in the wood is destructive to the fastener, how could
plating the fastener with a copper alloy help the situation?

You need an electrolyte (IE water and the other salts in the pressure
treated lumber) for the nail into wood to act like a cell and destroy
the nail. If the nail is completely coated in a copper alloy, it
won't react between the iron two metals (no electrolyte).

And for those of you thinking double dipped galvanized is a good idea,
look up Volta's pile.
