Adam Smith aptly likened money to the roads and wagons that transport goods, thus gratifying desires by putting goods into more convenient places.

The fundamental use that money serves is to apportion one's income conveniently as it accrues and as it is spent.

The use of money increases the value of goods by increasing the ease with which trade takes place.

Like any tool or agent, money is valued for what it does or helps to do.

It enhances the value of the goods that it buys and sells by dividing them into quantities convenient for use and by making them available at the right times.
