It also used to strike a good balance between rarity (which ensures the market won&apos;t be flooded) and availability (which actually made it usable as money).&lt;p&gt;Of course, most of this broke down as new, very productive, mines were found (e.g. in South America) and mining techniques improved. And nowadays we have the opposite issue: gold mining output declines, and is unable to follow the value growth of the world itself. This is one of the reasons why most countries moved first to fractional gold standards and then to convertible currency.</text><parent_chain><item><author>vladd</author><text>Any system of checks and balances will have its price.
