The question about how much you need to 'make it' depends on personal factors. The concept of metals being a hedge is, however many ounces are needed to buy x now should be the same amount in any future regardless of where fiat goes.
My take is to figure out exactly how much in expected expenses for six months I have, add a "comfortable" buffer for my lifestyle and local economy, and figure out how that translates to ounces of the metal(s) of my choice (Au, Pt, Ag, Cu). That should sustain me for the worst of whatever midden hits the windmill. Use the current prices for your PM(s) of choice to figure out how many ozt of each or a mix. Real-life numbers: I need $4k/month, so $24k in metals of choice.
