A monetary system could start as bartering. Or just exchanging resources. But eventually an "IOU" will show up and people will start exchanging them. And then you'll get our current monetary system.
Should it resemble our current world? Maybe not. But because of the nature of intelligent species as we know it, it's inevitable.
Hopefully, evolution will mold human nature to a level of allowing for a utopia
