Aristotle’s Principles of Sound Money

 Money must be able to withstand daily use and be resilient against forces of nature such as rust, corrosion and general wear and tear.  It must also be able to withstand extreme evets so that it continues to survive. 

Money must portable and hold significant value so that it can easily transported.  Ideally it should be able to fit in a pocket or purse and be convenient to use in daily life.

Fungible means that one unit of something is completely interchangeable with another unit of the same substance or item.  Ideally the substance should be so fungible that it could be completely reformed and resized without losing any mass.

Money needs to have value in and of itself.  There needs to be natural demand from the population to acquire and possess the item or substance.  Ideally the money would have practical and industrial applications in addition to luxury.

Money must be a risk-free store of value.  People earn a living from working their lives, and they need the best risk-free method of storing their labor.  Fiat currency is the opposite of a store of value, as continuous over-printing devalues the currency and people are forced to invest and take risk.

Money must be acceptable by two or more people involved in a transaction. It must facilitate the exchange of goods or services as quickly as possible.  Ideally the money would be able to be authenticated in a convenient way.
