The barter system had several significant problems that led to the need for money:

• Double coincidence of wants: Both parties needed to have what the other wanted, making exchanges difficult.
• Lack of common measure: There was no standard way to value goods, complicating trade.
• Indivisibility: Some goods could not be easily divided into smaller parts for trade.
• Storage issues: Perishable items could not be stored for long periods, leading to waste.
• Transport difficulties: Carrying large quantities of goods was cumbersome and impractical.

These limitations highlighted the need for a more efficient medium of exchange, ultimately leading to the invention of money.
