Final answer:
Money is a facilitator for the exchange of goods and services, not a producer of them. It serves as a medium of exchange, a unit of account, and a store of value. The double coincidence of wants inherent in barter systems highlights the importance of money in modern economies.
Step-by-step explanation:
Money is beneficial in the following ways: it is easily transported, available in several denominations, and widely accepted in commerce. However, money itself does not produce goods and services; rather, it facilitates the exchange of goods and services by acting as a medium of exchange, a unit of account, a store of value, and a standard of deferred payment. Money is at its core a tool that we use to trade effectively in complex economies, avoiding the impracticalities of the barter system, where a double coincidence of wants is required.
