My statement is not super constructive, but yes, I also really liked this article. Local-first, privacy, even the example of managing personal restaurant reviews.

I don't have enough meaningful thoughts here to contribute, but you & OP: I hope we can build a federated protocol for sharing stuff again.

btw, for historical context, the reason it is called "permissioned" instead of "private" is because there were sufficient people in the atmo that were very opinionated the E2EE is the only true private. It became an exercise in bikeshedding every time "private data" came up.
