THE REAL SITTERS ON MONEY ARE SPECULATORS WHEN THEY EXPECT DEFLATION. It only benefits them to "abstain" from both consumption and investment.
More generally, when they expect falling NGDP. The idea behind what you're saying is that suddenly the return on money (through expected deflation) increases. So it's now worth foregoing consumption and instead holding money, at the margin, because now it gives you a little bit extra future consumption. But if NGDP is fixed (or growth in fixed), then any fall in the price level (due to productivity gains) is accompanied by an increase in real output. So if NGDP is expected to remain on target, it's not actually worth hoarding money, at the margin. You don't have to forego consumption now to be rewarded with more in the future since you're already getting more by the higher real output, so you should consume the same amount now as you already planned. So NGDP remaining on target doesn't distort intertemporal decisions, irrespective of what's happening to the price level.
