Its interesting to pit them one against each other. My view is more entangled. Hierarchy is object based, rhizome is process based.
All agents that act need to crystallize their periphery, because analysis is necessary to partition out what to do in the infinitely complex, continuous process of nature. These crystallizations form the bases for individuals' frameworks to act. Crystallization itself is hierarchical.
The problem is not of hierarchy itself, but rather it is the uniform hegemonic imposition of a singular hierarchy across a domain. That imposition is what creates fragility.
I'd say the solution is not downward and inward, because that's still hegemonic but from a different basis. Instead, cultivating the generators that enable each individual to crystallize their own hierarchy to act into. The result is a fractal, mountainous terrain of clashing crystallizations that offer more possibilities than any individual framework could alone.
That's what Bitcoin and Nostr offer: enabling the multiplicity of individuals to act through their own frameworks while simultaneously allowing them to clash with others, rather than a single hegemonic declaration of who is allow to speak and what is allowed to be said.
