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.
Yes. Why would someone take your gold as currency when they can simply take your gold?
Wait, I thought it would be worthless? :)
