Really? Gold is the answer? Ulitmately against what, a weaker world currency?
No my friend, gold ain’t going to buy you food and water in a national crisis....its worthless.
Good secure shelter, a healthy stockpile of food, clothing, medical, toiletries, fuel, guns and ammo is how you will survive.
stockpiling gold is a joke, will get your broke, and will get you dead fast.
Every empire up thru the middle ages had a gold standard currency. I would say fiat money has a poor track record.
You'll jump like a clown dog for me, when the paper money is worthless, for a sliver of gold. You'll do anything for the gold then. Ha.
When in history has gold ever been worthless? People will always need a medium of exchange. Silver is more practicle for day to day transactions though. I suggest old dimes and quarters.
The things you list are essential. Anything more (e.g. a product from China or extra fuel to tool around with) will cost you gold. Why? Simply because those countries won’t accept our worthless green (and other color) backs. They only accept them now because of dollar and US military/intelligence hegemony. Once that is gone, there will be middlemen who will take your gold (or mine as the case may well be) and hand over a cool product or a nice amount of fuel.
