Economic system in theory

In a system where the resources required for survival in infinite in supply, without replenishing, and an existing economic structure is set up using a form of currency, would the currency, based on an abstract value, eventually become obsolete due to the abundance of supply, which in this scenario everyone can get the basics of and fairly easily learn to acquire ALL resources, leading to at best a system of bartering for those resources that one does not have time to, nor has the inclination to, acquire on their own?
