I just finished listening to the audio version of the book below. I am always so impressed by how Dr Ron Paul is able to so consciencly give a historical narrative of gold and side affects that it has caused. While giving  one of the most compelling  arguments to why we should return to free and open market for the money that we use. 

Why should we be forced to use the currency demanded by our Politicians ?Given the choice we would much rather trade in a currency that is back by something tangible say gold or  silver,in a competing market of coins/currency the best one would rise to the top and could theoretically be backed by anything. Bit coin as an example is backed by the time it took to complete the puzzle which earns the coin – I could be wrong here but thats how I understand it.
