I doubt it. There will probably always be some scarcity. Even if we remove (or effectively remove) scarcity of physical resources or energy, there is still only a limited amount of time. You could base an entire economy on time and you'd still need some kind of a medium of exchange. Even in Star Trek TNG, every schmo on Earth doesn't have access to Federation supercomputing clusters or their own starship.
