What makes money worth anything?

In order to understand the meaning and worth of money, or the economic crisis we are facing, one does not have to be an economist, but a philosopher. Thinking about and researching the worth of money, lead me to reading an excerpt from Atlas Shrugged by Ayn Rand. More specifically, it was Francisco d’Anconia’s money speech that really struck me with the power of its message, the depth of its analysis and the simplicity of its ideas.
