The fact that gold has been a store of money for basically all of time and that farmland and oil can both easily be priced in gold. Ever stop and think why china and Russia have been amassing massive stores of it? Eventually the fiat cash bubble has to end. Cash will lose its value when there's so much of it and the printing presses run non stop. What happens when those who buy massive amounts of commodities choose to do so outside of a useless dollar? In Venezuela after the dollar basically collapsed one oz of silver would have bought one person enough food for 6 months. One $20 ounce while fellow citizens are raising zoos for food.  They had plenty of oil though. You're missing more than you know apparently. Don't get me wrong though livestock and farmland are great to have too.
