> punishes hoarding Or put another way, punishes saving. Forcing people to "save" by loaning the money to businesses and governments bonds and equities is good for politicians who like to be measured by economic metrics. But it's bad for being able to actually save for the future, and reducing dependencies on banks, leading to the moral hazard (with 0% inflation you could have narrow banking without problems).
Or put another way, punishes saving. Yes, savings should have a cost and/or risk associated with them. Furthermore, it’s insane to expect otherwise.
Most obviously there is the time value of money. Money by itself isn't useful, only the things you can buy with it are. Something today is more useful than the same thing in a year.
Economists often act like none of the above is true. They argue that given an improving world people would just do nothing, hoarding money in the expectation of it being worth more in a year. For as long as I've been alive the 2% target has been justified with this sort of nonsensical circular pop psychology, in which supposedly devaluing savings was required to manipulate the people out of their naturally zombie-like state (which if true would obviously mean the economy wouldn't grow, acting as a negative feedback loop that would then make it immediately untrue again). The existence of counter-examples like Switzerland did not bother any of them. Now we read that this wasn't even the actual source of the number, it was just plucked out of the air and justified retroactively! Not really a surprise given the weakness of the original argument.
