'Helicopter Money and the Government of Central Bank Nightmares'

Simon Wren-Lewis:

Helicopter money and the government of central bank nightmares: If Quantitative Easing (QE), why not helicopter money? We know helicopter money is much more effective at stimulating demand. Helicopter money is a form of what economists call money financed fiscal stimulus (MFFS). In their current formulation independent central banks (ICB) rule out MFFS, because the institution that can do the stimulus (the government) is not allowed to cooperate on this with the institution that creates money (the ICB). In a world where governments - through ignorance or design - obsess about deficits when they should not, it turns out that MFFS or helicopter money is all we have left to prevent large negative demand shocks leading to deep and prolonged recessions. So why is it taboo? 
One reason why it is taboo among central banks is that they want an asset that they can later sell when the economy recovers. QE gives them that asset, but helicopter money does not. The nightmare (as ever with ICBs) is not the current position of deficient demand, but a potential future of excess inflation that they are unable to control. .... Helicopter money ... puts money into the system at the ZLB, in a much more effective way than QE, but it cannot be put into reverse by central banks alone. The central bank cannot demand we pay helicopter money back. [4] 
If the government cooperates, this is no problem. The government just ‘recapitalises’ the central bank, by either raising taxes or selling more of its own debt. Economists call this ‘fiscal backing’ for the central bank. In either case, the government is taking money out of the system on the central bank’s behalf. So the nightmare that makes helicopter money taboo is that the government refuses to do this. [1] ...

After explaining, he concludes

So this nightmare that makes helicopter money taboo is as unrealistic as most nightmares. The really strange thing is that ICBs have already had to confront this nightmare. It is more than possible that when central banks sell back their QE assets, they will make a loss, and so will be faced with exactly the same problem as with helicopter money. [3] A central banker knows better than not to worry about something because it might not happen. So the nightmare has already been faced down. It therefore seems doubly strange that the taboo about helicopter money remains. ...
