Barter – Why is Currency Necessary?

Imagine you wished to acquire coal, yet you only had fur or food to trade.
Imagine you wished to acquire a telephone but you only had gold to exchange.
This exchange is possible, but it’s extremely inefficient.
Standardized currency solves this problem by creating a form of exchange and liquidity that is essential for the way we have chosen to live.
Money may be stressful to some, but it is necessary to facilitate transactions and increase trade activity with expediency.
