Depends on what the scope is. It's a lot easier to go to the store and buy food with emergency cash if there is a 1 month blackout or internet outage. The grocery store isn't going to accept gold and the conversion rate from gold to cash isn't going to be great in that situation.
For inflation proofing a fortune, sure, keep a large chunk in gold (or something else that is stable and movable). But for "emergencies" I'd try to keep some cash.
If there's a long blackout or internet outage stores would not be able to operate - if you're preparing for that scenario canned food, water canisters, weapons and whatever else prepper handbooks say are probably your best investment.
