True, this is also why the Chinese continue to lend to us at basically a negative interest rate. Turns out gold doesn't really work that well for sovereigns (though China is #1 or #2 in gold mining).

Definitely that's what we've seen so far. In that case, we are only arguing about the validity of gold as a store of value vs. other investments (including straight currency holds). There is nothing particularly special about gold, the only difference is that mining companies can decide the rate of inflation vs. governments (but Australia...).
BitCoin is much more fair in this case as the rate of mining is basically fixed by complexity. There is not much difference between accepting someone's bitcoin vs. their gold, in either case its about trust that you can exchange the currency down the line for something else.
