What is the draw back of barter system of trade

The main drawbacks of the barter system of trade include:

1. Lack of Double Coincidence of Wants: It is often difficult to find two people who each have what the other wants and are willing to exchange it. This makes transactions inefficient and time-consuming.
2. Absence of a Common Measure of Value: There is no standard unit to measure the value of different goods and services. This makes it hard to determine fair exchange rates (e.g., how many fish for a pair of shoes?).
3. Indivisibility of Certain Goods: Some goods cannot be easily divided without losing their value (e.g., you can't trade half a cow for a small amount of grain). This limits the scope of exchange.
4. Difficulty in Storing Wealth: Perishable goods cannot be stored for long periods, making it hard for individuals to save their wealth for future use.
5. Problems with Deferred Payments: It is challenging to make agreements for future payments or credit transactions because the value of goods can fluctuate, and there's no standard unit for repayment.
