Gold would specifically not be a good choice in that situation, because you have to pay a custodian to deal with the gold and store it for you. That means either transacting in the original risky fiat currency any time you convert between the currency and gold (such as to buy things), or else transacting in the original risky fiat currency to get a foreign exchange to another currency and then transacting with a custodian - which defeats the whole purpose of converting the asset away from the original fiat currency that exposes untenable risk.
