In fairness, if the US dollar collapses, say, but the euro is fine and you find a way to get to Europe, you're much better off with a few chunks of gold that will be worth relatively what you bought them for than with wheelbarrows full of hundred dollar bills which are now worth less than paper.

Yeah, gold isn't worth anything unless a community agrees to assign a value to it, which probably won't happen in an apocalyptic scenario. If you really want to be prepared, you need to stock up on things that are actually useful:

• non-perishable, nutritious food (preferably something that has a lot of calories in a small serving so you could carry it on you)
• drinking water!! you would have to change it every once in a while though, so you wouldn't be drinking germ soup if a societal collapse actually happens
• durable, good quality clothing for various climates/weather conditions (due to climate change and the possibility that you would flee somewhere, you should preferably have clothing suitable for other climates than just the one you're used to)
• miscellanous supplies, like tools for building shelters, farming, making & maintaining different items, destroying things like trees or rocks to make space for building/agriculture or more likely, obtain materials. Things to protect yourself and your loved ones from the elements, like a good tent, sleeping bags, etc. Flashlights, powerbanks, batteries, water purifiers, multitools...
• knowledge. No matter how much stuff you have, it's no use if you don't actually know how to do things. Learn canning, blacksmithing, sewing, gardening, fishing, carpentry, foraging, and so on.

Bullets should be saved for protecting your community…trap and snare your animals :)
