It's enough for significant majority to strive for that type of society to stabilize this type of structure. Sure, some people don't like anarchist framework, that's why anarchists are propagating their way of thinking. Consider that we are from the beginning of our life indoctrinated into authoritarian structures like nation state, school, workplace and a lot of people go through the motion because they don't think alternative is possible. Probably not unsignificant fraction of slaves too thought that that's how it is. We know that slave owners were justifying slavery as natural, same as a lot of people justify liberalism as such. I would say anarchists want to create a world for anarchists and want to spread anarchists thought, because they think that there is actually nontrival part of humanity that would be to some extend interested in these ideas. Anarchism was very significant movement in the beginnings of XX century before it lost to Marxism-Leninism and these people were interested in these types of organization that prevent power accumulation. Marxism-Leninism damaged every anti-capitalist tendency in the west unfortunately in minds of big part of population, but I think it's still workable to spread the idea, especially considering that anarchists were repressed everywhere where Marxists-Leninists got to power.
