Interesting to note that weird economies are an important part of Bruce Sterling's work. Consider the AI-Tamagotchi-directed gift economy in "Maneki Neko" in A Good Old-fashioned Future.
Interesting turn of phrase I saw today: "This world of hundreds of millions of English speakers seems in its unstoppable immensity to [the French] to be consigning France to a sort of museum culture." I don't think it took the English-speaking world (i.e., Earth, depending on how you look at it) to make France a museum culture. Every society on its own does a fine job of trying to make itself into a museum culture.
