my dude right here is like "i'm typing with thumbs on a tiny device" while banging out "exhaustively," "convincingly," "electromagnetism," "centralisation," "industrialized," "catastrophically,"

god tier shit

It’s going to be basically impossible impossible to address this. You’ve asked incredibly broad questions and I’m typing on my phone with arthritic thumbs. Anything I miss or can’t exhaustively lay out convincingly you’ll just say “well what about that thing”.

Well, yeah - when you're advocating for a very radical change in societal structure, with potential downsides ranging as far as actual genocide, I feel like it'd be irresponsible to not point out flaws perceived in the proposed structure (or - lack of structure - as the case may be). You'll forgive me for not just taking your word when you say "we've got it figure out bro".

why if you want detailed answers you can really only find them in books

The trouble with reading an argument in a book is that it's a one way conversation. It's easy to present an idea in a way that seems totally sensible, when you're the only voice speaking. I don't doubt that you've ready many anarchic books that make sense when you read them, but the fact that you and others are having trouble distilling those arguments in a comprehensive fashion here shows that the arguments made in those books were probably not as compelling as you perceived them to be when you read them, but were just presented well (likely with a bit of confirmation bias sprinkled in).

I would say I’m not sure why you seem to think centralisation leads to superior manufacturing capabilities or agility in decision making

History and modern economics? Can you point to a modern nation that is heavily decentralized with a greater industrial base than it's centralized peers such as China and the US? As for decision making, I'll grant you that on small scales a lack of centralization works in your favor. Trying to get 100 people to decide on something is a lot easier than 100 million, but when dealing with a military or economic threat from a centralized power, 1 million separate decisions made by groups of 100 don't actually help.

It’s not as simple as big military beats small military, look how badly the usa failed in its various wars since ww2

True, though guerilla warfare certainly wouldn't be unique to anarchism. And while I agree the USA has failed in pretty much all of it's military goals since WW2, I'd point out that the targets of those military campaigns were completely decimated by the time they withdrew. Small comfort to your anarchic society that they weren't completely conquered when every village has been drone striked into rubble.

I'd also point out that the failings of the US military since WW2 has infinitely more to do with the fact that none of our wars have actually had meaningful objectives. During the cold war, each one had the dubious unofficial objective of "embarrass the SU", the wars in the middle east were fought for purely economic reasons (whatever might have been stated publicly), which is a goal they did actually succeed in.

As to not having an exact answer for every conceivable problem: it’s not like our society has one either. It’s not designed, we’re making this shit up and it is failing catastrophically to address challenges like power and wealth concentration due to technology, ecosystem collapse (we are in a mass extinction ffs), and climate change. Further it almost ended the world several times over during the cold war!

I don't disagree with this at all - but the fact that the current systems aren't working well doesn't mean we should just ignore problems in proposed alternatives.And ultimately i don't see how implementing anarchism actually fixes any of the problems you describe, given that all the problems you describe are fundamentally rooted in the flaws of human nature.

Hell, Climate Change in particular is one that would be basically impossible to actually solve in an Anarchic society. Say I wanted to build a super-polluting factory in our anarchic society, I go out where there aren't any people currently living, use my own resources to build said factory, and start polluting. Whose to say I can't? Who would even know what I'm polluting? I don't disagree that our current society is fucked - but just because the current system is broken, doesn't mean we should toss it out for a half-baked one just because it's different.
