Money has always been a particular problem for revolutionaries and anti-capitalists. What will money look like 'after the revolution'? How will it function? Will it exist at all? It's hard to answer the question if you don't know what money actually is. Proposing to eliminate it entirely seems utopian and naive.

Consensus isn't just about agreement. It's about changing things around: You get a proposal, you work something out, people foresee problems, you do creative synthesis. At the end of it, you come up with something that everyone thinks is okay. Most people like it, and nobody hates it.

The historical novelist has to consider what has actually happened, while the SF writer is dealing in possibilities, but they are both in the business of imagining a world unlike our own and yet connected to it.
