You are contradicting yourself here. First you say it is the goods that people value, not the money, but then if the value of money increased, people would just sit on it and not buy anything, presumably because they could buy even more goods if they waited.
Why would someone who prefers things to money deliberately withold his purchases? If I wanted a house, or to get married, or literally anything else that is important to me as a human being, I'm not going to postpone that just due to the increasing value of money.
Logically, if that were my strategy and money continuously increased in value, then surely I would save my money until right before my death and then spend it to get the most value. You realize how insane that sounds, don't you?
Yet your entire argument for the necessity of inflation hinges on this delusion. That people would not want to part with money for things because they would miss out on the increasing value of money.
Let's assume that we even accept your argument on its face for a moment, and say that devaluing currency to encourage spending over saving is a sensible thing to do at times. Surely there would be a limit to that right?
You wouldn't want to keep people from saving at all, since savings is where investment capital comes from. It's the seedcorn of the future. Yet look at how long interest rates have been at zero, and how much money is being pumped into the economy although we just had one of the worst shopping seasons in years. I would think that at this point even someone such as yourself must have doubts about the truth of your claims...
Watch as the continuosly poor state of the economy demands even more money printing, in order to "stimulate" spending...
