In the quote below who do you think the autonomous functionaries of estates are?

Today, we do not take a stand on this question. [Anarchists] today state only the purely conceptual aspect for our consideration: the modern state is a compulsory association which organizes domination. It has been successful in seeking to monopolize the legitimate use of physical force as a means of domination within a territory. To this end the state has combined the material means of organization in the hands of its leaders, and it has expropriated all autonomous functionaries of estates who formerly controlled these means in their own right. The state has taken their positions and now stands in the top place. The Last Paragraph is a Quote from Max Weber - 1946
