Hello @alxd , fancy meeting you here, welcome! I believe we had an exchange on Mastodon a while back. 
You have a point in your review – several, actually, and thanks @Tim_Reutemann for posting it. KSR himself admitted that referencing the b**chain had been a mistake. Rather than debating your impressive critique, I will say this: I never thought about Ministry as a prophecy or an attempt as a definitive statement about the transition to a non-doomed world. It’s just a near-future cli-fi novel. And yes, one by an author with his own obsessions and idiosyncrasies: the Mars trilogy has several references to the Swiss (as well as the Sufis, who do not feature in Ministry) too, with first-generation native Martian Nirgal visiting Switzerland in his ambassadorial trip to Earth in Green Mars.
As far the economics plays out, same story. In the great tapestry of Ministry, several things are waved through. Again, this is similar to Mars, where KSR resorts to having the economic model (“Vlad’s eco-economics”) explained by Coyote, a character that admits he does not understand it. In this sense, indeed, the organization of the Martian economy is only a narrative device: it enables the stories of the characters (for example Maya working for a water cooperative), but is neither explained nor understood.
Within these limitations, I still find KSR’s work – including Ministry – inspiring. For two reasons: one, he sets stories in economic systems we (and him) don’t really understand, but they are different from the late-stage capitalism we live in. If we find ourselves longing for these systems, then we can sit down and try to reverse engineer them. It is what we did in the Great Retrofit world two weeks ago.
Two – and this is specific to Ministry – he attempts to chart a path that takes us from here to a there where GNG emissions have been put under control. This is a fantastic contribution, and a major call to actions for economists and policy makers. Most solarpunk sci-fi starts in medias res, the transition has been accomplished or is underway (the mind goes to Ruthanna Emrys’s A Half-Built Garden – Cory Doctorow’s review is here). KSR’s dogged insistence on charting the entire journey translates well into the concept of subgame-perfect equilibria from game theory, and has been the inspiration for our own Sci-Fi Economics residency.
As a bonus, KSR occasionally even gets some economics right! For example, his statement that necessities should never be exploited for profit, because markets for human rights just do not work, is great. I found it echoed in subsequent papers, like this one (from 2023, so two years after Ministry).
So. Yes, let us by all means critique Ministry, but I would submit that its contribution is not (and was never meant to be) “getting it right”. It is to be thought-provoking, and in that sense, well, mission accomplished. You wrote a long review and even imagined a “perfect” version of the book; we organized an online discussion (three years ago!): and here we are, debating it again. This is what science fiction economics is about!
