Playing the devil's advocate

I identify as an Anarchist ( more leaning towards anarchism as a way of life). Not because I don't want a society that is non hierrachical, but there are some thoughts I can't get over. This is my main criticism. It'll be nice if you can find a counter argument.

"An egalitarianism narrative is complex, dynamic and ambigious.The paradox of egalitarianism is that it requires a homogeneity of mindset in a belief system whose foundation is plurality in other areas of living. This is incompatible with the fact that evolutionarily, we needed to have quick decision making to counter natural laws  so we evolved heuristics, and since evolution runs on "good enough”, taking into account the complexity and ambiguity of everything is too time and energy consuming for everyone to value it. Moreover, you need people who prioritize other things as different people have different strengths.  When it comes to narratives,  while the left  is more in line with reality, the right is more with human biases. A leftist world requires a level of tolerance to complexity and ambiguity that most people don't have, especially when considering the large scale globalised world we live in."
