> One explanation is that, as researchers have found, memories of hyperinflation have quite a bit of staying power. People in countries that suffered banking crises quite sensibly often prefer to save in cash [...] For the same historical reasons—they loathe debt.

This explanation seems absurd (or at least counter-intuitive). If your fear is hyperinflation the two things to do would be to avoid hoarding cash that can be worthless tomorrow and to buy as much tangible stuff as possible with a debt you will have to pay back with this devaluated currency.
