But currency as a concept isn't useless yet because we aren't post-scarcity yet. Yes, we are post-informational-scarcity (marginal cost of creating a new copy of existing digital information is zero). But we are not post-material-scarcity. And that matters because authors need to make money in order to purchase scarce material goods. I am not defending the various stupidities of the current copyright laws in the US, but the basic concept of "fake" prohibitions on unlimited copying still makes sense.
