I think we're past global collapse. That's some doomer shit. We have economies of scale. All that infrastructure doesn't just go away because of economic upheaval or global warfare.
FYI I have a bit of gold too and of course lots of firearms and a house of my own on about a half acre. There's nothing wrong with preparedness. But you priorities are very unrealistic imo. Have enough gold to bribe your way through a border, 1/2 an acre is plenty of land, any more is just dumping work into dirt so you can save money in an asset that's very illiquid and leaks value. Monero is a shitcoin with no real use case.
Own as many guns as you'd like though, I don't have an argument there 😂
