Money is just a game coin. The aristocracies need it because they need someone to provide services to them. By creating that bond an economic and currency system has to be created as well. But once they don't need people to provide services, well, they can remove that system too.
That pretty much means the end of everything for ordinary people and the beginning of the "Lord of light". That also means that humans probably won't be able to go through the great filter -- yes I believe it is not a scientific filter, but a social one.
