Ooff... Self sovereign digital identity is huge in the cyberspace.
Self sovereign digital money is huge both in cyberspace and meatspace.
I wouldn't claim one is more important than the other, taking the violence monopoly out of the hands of a few seems *at least* as important or even more than not allowing them to define your "digital identity".
While they are powerfully linked in the cyberspace, the money doesn't need identity in meatspace.
Nostr is doing extremely good for the cyberspace, but not everyone wants to be here, and that's totally fair.
Meatspace should keep being the most important space and improvements that make life here better are more important than the ones that make it better in the cyberspace imho.
