What is the purpose of money?

Hi all,

I have the following argument regarding the purpose of money, does it seem correct to you, or am I wrong in my reasoning?
All feedback welcome, but please, keep it classy.:D

What is the purpose of money?

1. Trade with money or barter with products: You can trade/barter some chickens for a haircut or you can trade some money for a haircut.
2. Why not barter products for products: Chickens are uncomfortable to carry compared with money.
3. Definition:Money reduces the time and effort needed to trade.

Reasoning:

1. Common sense: It is common sense for humans to try to reduce the time and effort spend on activities they do, so that they make their lives easier.
2. What is trade: Trade is defined as the interchange of products between people.
3. Problems with bartering: Trading products for products requires a certain amount of time and effort spend. How much time and effort depends on the specific products used in the occasion, and it makes the problem even worse, as it is difficult for humans to plan their actions.

   • Trading chickens for a haircut is easier than trading a venomous snake for a haircut (unless the barber has pretty weird taste...).

4. Money as a medium: In order to reduce the amount of time and effort spend in trading, a new product is introduced, which on its own doesn't hold any value, apart from the value that people agree it has. This product we call money and it comes in more than one form (physical money, plastic money etc. )
