He wobbles of "saving" and "investing". Sitting on a desk, having worked his whole live beyond a desk and never for a free market enterprise, he tries to understand capitalism.

Do you remember his quote: "

“Credit expansion can bring about a temporary boom. But such a fictitious prosperity must end in a general depression of trade, a slump.” — Ludwig von Mises

Wow. Look who is talking. A master or an idiot? You never know. Out of curiosity, can you show me an economic boom that does NOT come with a credit expansion? The sentence is a tautology. Meaningless. "The Banana is big but it's shell is bigger". Wow.

Uh, huh...

What he is talking about is the boom-bust cycle and not whatever you're claiming which, honestly, I have no clue.

There are no real insights by Mises, except an extraordinary well description of a free market, middle ages, barter economy.

That and a devastating attack against socialism (from which they never recovered) which is the very reason you felt the need to engage in ad hominem attacks...

But, alas, if had ever actually read anything he wrote you would see his insights don't really apply to a barter economy at all -- unless they want to do something crazy and solve the coincidence of wants problem to evolve into an actual modern economy.
