I do see the points u are making & to a degree they are valid. The difference that I see is the lens that u look thru when u are seeing Global Issues.
1 of the biggest Global Issues thru time has been TRUST. How do u settle a trade with a party that u do not trust ? When u look back thru Time/History, GOLD/Silver has provided the answer.
The value of Gold is not imposed by any one entity. The Value of Gold has developed naturally thru Millenia of human interaction. That Says a lot to me & I think it's too Significant to ignore.
Other Eras & Culture have had varying relationships between Gold/Silver & Fiat Currency. The Fiat Systems come & go throughout history & no doubt into the future, but when needed Gold/Silver is always there for the transition when Trust is broken & trade is still required ( eg, the USA is still buying Nuclear Fuel from Russia )
Whether that trade is between individuals/business/company/industry/states/nations Gold/Silver is generally the fall back until a new System is devised/implemented that places Gold/Silver into the background again :- for a while.
I hope that I NEVER have a need to use my PM Stack, because that would mean trust has been broken & there is turmoil about. If that does occur, I have my PM Stack to help me & my family, to hopefully, make it thru that period of turmoil.
I'm 63 yrs & in AUS, so have seen some turmoil, but thankfully not war or Significant enough turmoil that has broken the current system. I keep a thought in mind though. I would think that after WWI finished that the people of Europe especially & the rest of the world believed that they would NEVER suffer another World War. Yet just 2 decades later, WWII.
So my PM Stack is my fall back for when " it's NEVER going to Happen " does HAPPEN ( if that makes sense )
