Yes, for very short periods of time, ideally. To the extent that remains true the effect of inflation is smoothed out. As at each stage in the transaction chain prices can adjust pricing to reflect inflation. Think of it like a continuously variable transmission. Yes, it has gears. But the effect is basically smoothed out if you do it quickly enough.
> Saying “don’t hold money” tells me everything I need to know about your understanding of economics.
It clearly doesn't.
In such an environment you want to get rid of your USD as fast as possible and turn them into something you value, whether it be land or whatever. The money itself is by design an inflationary currency. Most people don't understand this, which is just fine with the people who print the money and the ones who distribute and loan it out.
Now, having lots of liquid cash AKA liquidity is a good thing as long as you get rid of it soon by putting it in assets. Lots of people gladly go into debt taking out loans to buy productive assets and declare bankruptcy multiple times playing this kind of game. It's kind of insane in a way.
The idea is that you use it to invest: into real estate, into equities, into bonds, heck even a savings account collateralizes mortgages. Yes, even your magic beans represent the system working. The system is designed to encourage the continued survival of the most economically fit companies, etc, by your picking winners.
Don't hold money. Certainly not more than you need in the event of an emergency.
