Yes off course, because that is the basis of the whole thing. In the past (or may I say history) we used to trade simple stuff with one another instead of the money. These things were nothing but stuff which was readily avaible in the nature itself and thus life was far easier.
But now we have controlled financial system, economics, tracking system, currency with validity of authenticity and much more. We cant trade anything above that or below that and thus we are more or less restricted to use it.
If you dont use money then no one will ever value you. Now you cant go into the grocery store and ask for something in exchange with your hand made tools etc etc.
That make sense money is far important.
Money is a medium of exchange and we should keep its function as it is. The problem is, some people go way beyond that and use money for other purposes such as a way of gaining power. Greedy and power hungry people with their exploitation/pursuit of money through unlawful and unethical means. We should just stick with money’s function as the means for us to attain goods & services, and nothing else other than that.
