The people that post here have all got heavy bets on a stable financial system with the US in the lead. We bought into it and can't even think of the system leaving us hang out to dry. So if any other idea comes-up other than "it will be stable forever", the cognitive dissonance that arises is too much to bear, and the discussion goes to loading-up on food and ammo. There's a lot of room between something other than the stability we've enjoyed and food riots, but that middle ground never seems to be discussed.
Well put, Seng.
I think real estate will be a decent hedge for many of the scenarios between the status quo and mass vagrant uprisings. Only an investment if you have and can keep tenants. I instinctually like the idea of acquiring durable goods, but with ongoing world industrialization, goods should just continue to deflate in real cost.
And as others have pointed out, if things get so bad that you wish you had bought beans, bottled water, and bullets. . . Well, appropriately hedging against the USD will be among the least of our worries.
