To accept a fully cash free society you have to acknowledge a totalitarian government as completely free of wrong doing or accept your slavery as law. There may be another way around this, short of barter, but I haven't considered it, yet. Without cash, reconstruction of credit or value in society can't be accomplished.
Even Microsoft with their insistence we adapt to their new operating system has met with incredible resistance and it has taken two operating systems for them to come to terms, they realize who keeps them in business. The British discovered they weren't going to be able to keep the 'Colonies' as their cash cow when the people rebelled.
If this is really something to be concerned about, I don't think we will be able to bring a viable solution to the table short of non-compliance.
