Banks, Iain M. The Culture series

Iain M. Banks's Culture series. Notable for its post-scarcity civilisation: anyone can have pretty much any good or service they want. Nobody has to work unless they want to. Work has more to do with self-expression, self-fulfillment and relaxation than with toil, coercion, duty and necessity. Banks outlines the Culture's democratically planned economy in "A Few Notes on the Culture" (1994). See also Gene Roddenberry.

Here's one interesting snippet: in Banks's Look to Windward (2000), a highly desirable ticketed music event leads to a "partial" reinvention of "money."
“Well, for tickets to Ziller’s concert [...] People who can’t stand other people are inviting them to dinner, booking deep-space cruises together — good grief — even agreeing to go camping with them. Camping! [...] People have traded sexual favors, they’ve agreed to pregnancies, they’ve altered their appearance to accommodate a partner’s desires, they’ve begun to change gender to please lovers; all just to get tickets [...] And they have indeed [...] come to agreements that go beyond barter to a form of liquidity regarding future considerations that sounds remarkably like money” (p.276).
I wrote about this a little bit in the reflective part of my PhD. I said:
"This episode suggests a technologically privileged and sexually liberal version of commodity theory, with the same progression from inconvenient, illiquid, spot-trade barters to more conveniently liquid transactions. The tenacity of money in the Culture series, flourishing inside its homines economici like gut microbiomes [...] suggests a failure to fully erase money."
