e/acc isn't a serious idealogy but is kind of just a bit with some philosophical backing. Its definitely a lot of fun.
Its a bit unrelated, but I don't think your statement about capitalism being a result of human choices is correct. Capitalism is the emergent property of a multi agent resource collection game where one's resources compound in proportion to their quantity. Its the outcome when agents don't co-operate.
The best quality of life features of modern society, such as human rights and safety standards, only emerged due to coordination working against the forces of capitalism.
