Money is a thing without which it is almost impossible to do in this world, because all we need is acquired exclusively with money, therefore, to say that money is not any significant thing can only Robinson Crusoe who lives on a desert island and eat bananas. All other people need money.
Money is transaction tool. When we live in community, we do trade and we need money as tool of transaction to make it more easier. I think money still important as long we live in community.
