Op, I appreciate that you seem to be genuinely interested in these topics, and are not just farming engagement (which is kinda meaningless here on the Fedi, anyways…). If I may offer a suggestion, try to find a tone that doesn’t sound like a roadmap for some corporate brand strategy. Most of us that are here and would be interested in a “fediverse permaculture” are severely put off by the structure of your post, not to mention it lacks in depth for most suggestions to be directly actionable (for example, the merch you would sell to support the insurance still needs to be made somewhere, by someone, who either needs to be paid for their time or are already independently wealthy).

Have you taken a look around !permacomputing@slrpnk.net ? Permaculture is not just about principles of mutual support but also a long process of experimentation to see which combinations of which plants and practices works out “for the best”. You might foster more of the conversation you’re looking for if you can bring some more concrete examples or proposals to serve as topics instead of an all-encompassing manifesto post.
