I think that argument is against some hyperinflationists' argument that the US gubmint will borrow and spend it's way out of deflation.
I'm a stagflationist - my guess is that CBs will drop IRs so low in their attempt to recapitalise banks that, faced with a tsunami of ultracheap USD & GBP carry trade money, the banks will bid up food and energy prices, and fund a mass of renewable energy start ups - a replay of the housing bubble (bidding up essentials, but food & energy this time) and the dot com boom (but funding renewable energy companies this time around) combined. Sovereign Wealth Funds will inject a lot of capital into the next bubbles (but mostly at home) along with the CBs.
