Reality check time: as of now, the paper currency getting hit is the dollar. That's the trade.
But the dollar will "recover", as the next paper currency gets hit, the euro (most likely, especially given today's events, which shows that the entire ECB board is a bunch of utter stoops), the pound or the yen. (The commodity currencies, the rand, the loonie, and the Aussie and NZ dollars, will probably do OK, but it'll be chancy even for these.) This will mean that inflation, as measured conventionally and in dollars, will recede.
It'll take a while, but eventually the lesson will take that all of these, not just the USD, is in deep, deep water, with no obvious means of rescue. As that lesson slowly sinks in, just keep buying gold on the inevitable sharp dips, because in between one or more of those dips, the shot up is going to be breathtaking, regardless of which piece of paper you call legal.
As for these folks who can't make ends meet: they've been unnaturally quiet, but that's about to end, and for most of the folks on this board their awakening is not going to be a pleasant thing. Watch out.
