This is generally my take as well, though I think there may be a place for it, as another layer or for localised systems… I don’t really know, I am not much of a financial person. I think it just needs to marinate a bit to find its niche, though. Monero seems cool for transactional stuff and I have played around with it a bit. It definitely has very limited use cases, though. I have a good friend who is an anarchist (defo not ancap, though) who is interested in this stuff, and I have chatted with her quite a bit about it, but I think she sometimes does not see the tech side clearly and I frankly think we need the somewhat fluid nature of our current systems as you mentioned more than we think. It’s a cool idea anyway.
Now, I admit I am stupid on this stuff and may be missing something (please correct me), but I am quite interested in ideas about regulating power and data aspects of cloud computing with it, however, maybe as a way to earn something for crunching while idle like Gridcoin; maybe for environmental reasons (less local hardware) too… Remember SETI, those old screensavers that looked for alien life in the 90s? That’s where they are now. The projects that they have whitelisted are super interesting: gridcoin.us/guides/whitelist.htm I think that there are others like this too, but I have not gone down that rabbit hole. Even for just a closed circuit like universities, government-wide public services (large-scale GIS and flood modelling in underfunded areas!), NGOs, etc… I am less convinced about how people are trying to implement it with AI stuff or any kind of daily retail, currently anyway. Anyway, that is where my brain has gone with that one. I played with Gridcoin, and it was a fun little experiment, but I didn’t want to fiddle around fixing it after something broke. It isn’t monetarily really worth anything, anyway.
