Thinking of wealth systems:
Eclipse Phase has several systems of money including reputation based wealth (as you referenced about “what some transhumanists want”), it shows a reputation-based economy in a way that gamers can understand (so it beats several leading transhumanist essayists on that score).
The Profit Factor (Rogue Trader)/ Influence (Dark Heresy 2nd edition) replaced the book-keeping of money with having a stat that you roll against with a modifier for how rare stuff is, and modified by your skills in trading. It’s pretty good for abstracting money and getting stuff in the grim darkness of the 41st millenium (and the Rogue Trader version modifies for scale, so you can equip regiments with small arms or buy new space ship parts).
Original Conspiracy X was great on two fronts - it had a mechanism for building a base, and the stuff in it was bought with points based on character’s Influence stat. The sorts of things it could buy depended on the sort of influence - Science is great for getting lab gear and computers, but it won’t get you guns, where Criminal influence gets you stolen guns, Police influence gets you law enforcement level gear and Military influence gets you the big guns. The other front was pulling strings, so having a day job with useful influence was great - are you a law enforcement officer who can get access to evidence and crime scenes? Can you use your security clearance to get into all sorts of forbidden places? Are you so high up in the conspiracy you can borrow alien artefacts?
Sadly, the 21st century has disillusioned me to Conspiracy X - the conspiracies of the 2020s are more batshit crazy than those of the 90s, and government power in the US seems a curious thing - I no longer believe the CDC can enforce a quarantine (whereas in the 90s we were certain, like in that movie Hotzone!) and the FBI may not be as apolitical and competent as we thought.
