So why can't the EAA offer an STC that calls for the replacement of
parts that are attacked by ethanol? From my talks with the EAA they
are just going to let the mogas STC die.

Most likely because going through the entire fuel system of an airplane
to ensure everything in there is unaffected by ethenol and proving
it to the satisfaction of the FAA is a huge undertaking for one airplane
let alone the more common models of the GA fleet.

Add that on top of ensuring the engine itself runs properly on fuel
with ethenol to the satisfaction of the FAA.

Or in other words, money.
