You can't eat your home fire insurance policy, either. Gold is a financial hedge, not a survival supply.
Ah! I misunderstood. I understand it is possible to trade in gold without taking actual possession. If you time it right (good luck or foresight) you can use it as a pendulum to temper the shocks of the investment market and currencies that seem to be based on faith and fumes.
GLD (SPDR Gold Shares) is an ETF (Exchange Traded Fund) you can use to invest in gold without taking physical possession. SIVR (abrdn Physical Silver Shares) is a silver ETF.
Physically holding gold or silver has its advantages, but you pay a premium on both the purchase and the sale, so it has to go up substantially before you recoup your initial investment.
You can check the trading price of either of these (and pretty much any other stock, ETF, or mutual fund) at -
