In order for money not to be “the evil and the crown of all evil,” one must learn how to use it.
Money is just a tool, an essence.
Once people were afraid of fire. Then they realized how to get it and how to control it. Some began to use it to cook food, to heat their homes. Others to burn forests and other people's homes.... And so it is with money - for some it's a master, for some it's the purpose of life, for some it's an asset for which they would do anything... And there are those who use it for development, for investment, for increasing their capital.
Evil is the people themselves who use some solutions for evil, although they can use them for good.
PS And the task to dreamers about moneyless system of building society: model how the world and your life will look like if you remove the measure of value in the form of money ?
