But you may ask why have inflation in the first place? why money print?, this is done to have velocity of money, meaning it promotes people to spend and not hoard money, giving incentive for people to actually start businesses to catch some of that consumer spending.
This isn't an explanation.
If individuals in the market wish to defer consumption until a later date, or wish to invest in businesses (perhaps interest from a functional lending bank rather than one addicted to cheap debt) why is that some kind of market failure?
Perhaps excess consumption and environmental catastrophe, as well as impending poverty in old age, is a consequence of this.
Keynsians have such a wacky interpretation of economics and the free market.
