Why do you believe in it, do you approve it in theory or also in practice? I think a lot of people approve of anarchism in theory but rejects the possibility of it to be put in practice unless we live in an utopia.. which I don't think we do, unfortunately. Maybe techno-anarchism would be more practical? Technology is such badly regulated and ordinary people are punished harsher than corporate so I really think techno-anarchism deserves a lot more attention (not saying anarchism itself doesn't) I see a lot of people here are more knowledgeable than me so don't take my word so seriously, maybe I shouldn't be expressing my idiot thoughts on it, or maybe just embrace it and ask regardless of any shame I might get.
I'm not trying to be mean to anyone, just genuinely wanted to discuss with whoever is willing to chip in on the topic.
I think the most important factor when it comes to that issue is free association and, like you said, decentralization. Ideally we would see coordination rather than hierarchy; no one has to be in charge- there are simply roles that get filled. There are even guides online
It's my understanding that the US military is as capable as they are on the battlefield largely due to the autonomy each individual unit is granted.
This is where things start to get out of my wheelhouse though, but it seems to me that if enough people want this kind of change, we could make it happen by enough individuals simply pitching in
