Even if no change could ever be made again to Bitcoin: it is not an inflationary money in the long term. Only during the current predictable and necessary bootstrapping phase where there still exists a block reward (until ~2140) is the total circulating supply gradually increasing. After this point it is neither inflationary or deflationary for supply reasons (although as people lose coins it may be very slightly deflationary).
