Suppose, just suppose, that you believed that printing money was irreversible, or just very hard to reverse. So central banks could increase the supply of base money by printing money, but could not (or could not easily) reduce the supply of base money again by burning money.
And suppose you knew that central banks had been printing very large amounts of money recently, because of special circumstances. Which they have. And suppose you thought that those special circumstances wouldn't last forever. Which they probably won't.
Would you be really scared of very high future inflation? I would be. Would you be saying that central banks should stop printing so much money, even if it did mean that aggregate demand is too low right now? I think I would be.
