Why is Money Necessary? I've heard a lot of different economists bullet point a few main ideas as to why money is necessary. However, I'd like to get an ultimate rundown list. What are the major reasons why money is necessary for a culture to thrive?
There are issues with this question as currently written. 

I will attempt to offer a partial answer by responding with a different question. If money did not exist, how would governments in modern developed countries impose taxes?

Historically, rulers would impose taxes in kind: forcing peasants to serve in the army, or taking a portion of the harvest. This is not particularly easy to see how a modern government could achieve this in a politically acceptable fashion.

So if you can find a way to allow taxation without money, you have found a way for money to not be necessary in a modern developed country.
