In a Utopia built on absolute trust, then, yes, currency as we know it will become obsolete. In a future where we have truly infinite resources (perpetual energy and food/water supplies and maybe even luxuries), then yes, I can see it happening. The very first step is to abolish the system of haves and have-nots. Since if YOU discovered a source of perpetual energy, won't you jump at the chance to monetize it?
But we all know that is next to impossible. Besides, for all its (literal) worth, the invention of Currency actually changed the course of history, otherwise, your PS4 will probably be worth 4 chickens and a cow. Or 4 cows and a Chicken. Or 3 Pigs. Or..... You get the idea.
