It wouldn’t.

Anarchism (and communism) live and die by the idea that ALL people would have a completely unrealistic level of cooperation and selflessness. As fucked up as capitalism is, it can bend when people don’t play nice and there’s at least a theoretical possibility of anyone gaining power (money) to impact change in the system. Money itself doesn’t inherently have preferences or moral opinions on what should be. Anarchism however breaks the moment someone behaves selfishly. It can work fine in small, like-minded communities where people can always leave (or be excluded) to find other systems that better fit their ideals. However, Anarchism on a societal level would demand that there is basically no other type of society available - which would lead to Sen’s paradox. The reason we don’t have true anarchist (or communist) countries is that they get wiped out by powers that function in sync with people’s natural inclinations for self-interest (like capitalism). People like to argue that these attitudes are DUE to capitalism, not inherent in human nature. Even if I were to entertain the idea that that’s true, we currently live in this world of self-interest. Unless you can press a reset button on humanity, this is what we are working with. Solutions that rely on the idea that we can just fundamentally change how ALL people in the world currently are, are not solutions. They’re idle fantasies. The “argument” that “if not for how the world wasn’t shitty, we could have an amazing utopia”, is not an argument at all, it’s just a tautology with no power of utility.

The way db0 handled their defederation from feddit.org is a great example of how Anarchism fails even on small scale. They espouse ideals about democratic voting and rational discourse, but the moment the organizing body of the instance had opinions on how they think things “should” be, they used propaganda and political theater to get the result they wanted. Anarchist ideals couldn’t function in a low stakes online space, it has little hope of functioning where people are driven by actual, survival needs (and desire for power). Whatever ideological purity drove the db0 admins to present the “democratic vote” the way they did, will be the exact same drive people tend to fall to on larger scales as well.

Same thing can be seen in the Communist instances: they rely heavily on propaganda and people sticking to the “correct” narrative. Which also brings up the conflict: there has to be an organizing body that has opinions on what is “right” and what is “wrong”. This organizing body will be the authority, no matter how people try to use rhetorical slalom to get around it and trick people into thinking the spade isn’t a spade.

People can start to build small grassroots communities with these ideals. Please do, and once they gain enough power (money) in the system we are currently living in, perhaps they can impact policy changes etc. that are more humanitarian. That would be wonderful. But always be aware that the ideals are fragile and break under any corruption. Capitalism works with corruption, which is why it’s extremely effective at being the might that makes right.
