I mean, my take is that hierarchy is something which will inevitably occur whether it is planned or not.

yeah, you have to plan to eliminate it and work hard to keep it from cropping up. this is what the Tyranny of Structurelessness is actually about. anti-hierarchical organizing techniques exist to build relatively flat, cohesive, and functional groups but nothing happens accidentally and you sure as fuck aren't going to get there if you haven't read theory.

the flipside is that the benefit of doing so is how utterly pleasant these groups are to be in and work with. it's literally easier to get things done when the people who need to do a piece of work are the ones empowered to make decisions about it.

trying to build orgs without anarchist theory is like trying to overthrow capitalism without reading Marx.
