I believe that if there ever becomes a consensus that Bitcoin’s inflation parameters were a show-stopper for the Bitcoin economy, that the power to correct it lies with merchants, who would vote for changing the rules. I believe they would do this not by changing Bitcoin, but by accepting, in parallel, a brand new alt coin that reflects the consensus as to how the inflation should be. I believe such an alt coin would have its genesis at around the time that consensus moved toward accepting inflation, rather than adopting the seignorage of some other alt coin out there today.
