Money rules the world because humanity has not yet reached the highest point of development. The ideal system of exchange is barter (everyone does what he can for the common good). But people are too distrustful to switch completely to this system. Money is the simplest form of exchange, but it is also a means of enslavement.
It was the inconvenience of barter that led to the emergence of monetary relations. Barter is possible only in difficult economic situations, and for large players.
Now I will explain very simply - you make buttons, your wife makes toothpicks, and your son makes hoses for watering the grass. Describe the process of bartering in order to realize, for example, your dream - buying a new car. More precisely, not a purchase, but an exchange of what your family produces, for a car, from the manufacturer's digging? Believe me - very quickly you will understand the fallacy of your opinion
Well, or even bring the steps to achieve your goal?
In the world of money - this is extremely simple - you sell your products on the market, who needs it. You get money, go to a car dealership, and buy a car for money.
And how will it look in the scheme of barter relations?
