Though a thought for all those people who call "gold bugs" out in the open.
When Warren Buffet was writing in regards to investing in gold or real items for growth, there may have been some confusion.
Currency, ones like the dollar, and this Zimbabwe 'unit' are of the same premise. A piece of paper; of which perception of it's said worth is key.
