I think you raise interesting points.
Imo, the reason because it looks like the community is focused on hierarchical governance is because what is being discussed is how to channel $ from point A (NF) to point B (communities), and how that model can survive the eventual disappearence of point A (as seen with other level 1 blockchains).
However, what you suggest highlights the limits of such a model. Focusing on communities who are able to implement positive models for the empowerment of individuals is imperative.
DAO Verticals should be, imo, a fair representation of the communities they support, and not an external authority, that eventually mimics traditional models of governance.
