It's bizarre these so-called conservatives at the WSJ have abandoned Chicago style economics for gold-bug reactionary alarmism.
The monetarist theory--now the dominant theory of monetary policy--is that one of the biggest, most economically important features of a recession is a flight to liquidity. In such a situation, the demand for tangible money--and, under US law, there is none more tangible than the dollar--will drastically jump, despite a limited supply. Nobody doubts the tangibility of the dollar when they are forced to pay taxes, and if they do, they might find themselves in a cell with a tangible lock and 6 by 6 tangible feet.
The correct thing to do, then, is to expand the money supply. This might happen by a seemingly alarming amount, especially given the highly leveraged nature of our economy. But otherwise a flight to liquidity will shut down the financial system, cause huge losses in "safe" bank accounts and funds, cause massive deflation as money becomes scarce, and cause a nasty depression--which is what happened from 1929 to 1932.
The money supply has expanded from about $800 billion to $2 trillion. Alarming? Maybe, but
1) we're not seeing inflation yet
2) most economists agree that the Fed contracting the money supply was a major cause of the 1929 Depression
3) the Fed is perfectly willing to stall the economy to prevent inflation, which is what they did in 1979 when a shameless monetarist finally was given power. See: http://en.wikipedia.org/wiki/Paul_Volcker#Chairman_of_the_Fe... . It's worth noting that Volcker is one of Obama's chief economic advisors: the guy in charge of economic recovery board.
4) the amount of paper cash has increased by a "mere" 120 billion or so. Most of the remaining cash is sitting in Federal Reserve bank accounts, not being used.
So I wouldn't dump greenbacks yet. If you're like most people few of your assets are in greenbacks anyway.
Finally, if I keep seeing articles like this, I'm buying puts on gold. You heard it here first, folks.
