Yup and thankfully now we have so many different money systems that one can decide where to keep their value. People need not keep cash under the mattress if they dont want to. You can hold scarce assets that appreciate over time and only hold inflationary fiat when you need to purchase something. Thus you will never be pressured to spend all your money because most of your "money" isnt being held in inflationary assets.

We are told that inflation is good because it encourages spending but i would argue that such an effect is being dimished because many deflationary assets are traded on liquid markets.

That's kind of the point, right? Inflation encourages spending, but it also encourages investment, and your saved money can be invested in stocks and bonds, which also stimulate economic growth more than being stuffed in a mattress.

The crash of property prices in Japan recently is an example of deflation in action and its long lasting negative effects.
