I believe people are like this due to the conditions they live in. Capitalism is a system that encourages selfishness in order to survive. I whole heartedly believe that if conditions changed, people would change. Not immediately of course. No anarchist is saying that it wouldn’t be a rough transition, or that it’s a flawless society, or any of that. But we do think that it would work and that it’d be better in the long run than what we have rn
Nationalizing the economy goes against anarchist ideals due to nationalizing means giving it to the government (entirely contrary to anarchist thought). The second one, even after the “trial period”, has ended is still taking the fruits of your labor. Under anarchism, there are no companies. They are free associations of workers. The workers who work the capital own the capital. And there isn’t money, that’s contrary to communism and no matter how you split it money is unegalitarian. A worker keeps what he wants from his labor, and communalizes the rest. And is thus entitled to what he needs from the community.
Edit: Rojava is also not an anarchist project. At best it’s a libertarian socialist project. And I’ve never heard of this “trial period” stuff in anything I’ve ever read about and anarchist example
