> Money is not wealth. Money is a tool.
Can you please stop making up your own economics? A currency is an asset. End. Of. Story.
Deflation is a directional property of an exchange rate between a pair of assets.
By "used" you mean traded. And yes trade increasing (of which consumer spending is a kind of trading) is a good thing. You only get that with volatility. This can be created through an inflation but dually it is also created through deflation.
There is nothing wrong or immoral about a particular asset going up or down in price relative to another asset.
This unscientific stance of considering all deflation as immoral is based on absolutely nothing except emotional propaganda.
You have provided exactly zero proofs verifying that any and all deflation in a currency is a bad thing. And you will never be able to provide such a "proof" because it does not exist.
Let's see if you are even capable of constructing a proper intellectual retort. My doubts run high.
