Physical gold is good to have in a collapse govt scenario.
Not as good as physical lead and brass
I hate to disagree with one so wise, but the gold MIGHT be good to have AFTER government is restored - but during the collapse?
As soon as you attempt a transaction for some necessity - like food, or energy - dozens or maybe even hundreds of people will be looking to kill you to take the gold. Trying to use PMs for transactions in a collapse scenario is like painting a target on your back.
If you have a plan to escape to somewhere where you could SELL gold for currency, THAT works.
