You claim to know with great detail and certainty what anarchists believe without citing any anarchist thinkers. All you are doing is constructing a strawman of anarchists based on vibes hoping that none will be here to refute it. Anarchy is more than the absence of the state, and none who are knowledgeable posit that anarchy will materialize without effort. Anarchists are idealists not out of naivete, but necessity. It has been born out of history that when means and ends are not unified, the means become the ends. This was true of the Russian revolution when "all power to the Soviets" became hollow words and "war communism" became the new oppressor of the people.
