Yeah, there's an economist comment on "We can afford everything that we produced".

Like when the Apple is produced it's not because a dollar bill was sowen into the ground. The actual inputs of production are not money but money is the lubricant that allows the goods and services to flow around in the economy. We always run into the situation where goods and services are produced and not demanded and that causes them to no longer be produced but the lack of money didn't cause their existence no more than money produced them in the first place.

Without it, societies had to have informal debts where you knew you helped your neighbor harvest crops so they would later do something for you (or perhaps you helped them harvest their crops because they provided shelter). That whole barter shit is made up.
