I discussed that with someone last weekend when peppers was on TV.
I get the argument, problem is if the monetary system.collapses the short term result is total chaos and everything devalues for average Joe. You can't use gold on the street because it has no value, can be faked, can't be weighed, it's useless.
WWII people swapped jewellery, diamonds, Gold for food and water. But diamonds are worth 2000/ct.... Nope, they are worth what the owner of the food says it's worth. This has been done before and history repeats. The rich with all the jewels and gold were instantly poor because in civilian life it's useless yet somehow people believe it's different now.....
The biggest trick is a monetary system is based on belief.... I believe the digits in my account are money. I believe he plastic notes in my wallet is money. Everybody else around me believes it. Go and grab your Gold bar and ask the same question. If everybody aggrees (which they won't), go one further an swap $100 gold for $100 cash and.see.who takes up the offer.... NO one will. Walk into a bank, give them 100/gold and exchange for a 100note, won't happen. Today its merely a store of.value, nothing more. See my point?
Money is belief. Livestock was once money. Grain was once money. Gold was once money. Coins and paper notes are money today.
Gold has value before a collapse, not after for average Joe . So the trick is to get out and buy whatever it is you need before be it land, food etc.
