In the most interesting of ways, Marx would reject the calls for a utopic society. He would dismiss them because they lacked his full throated embrace of the dialectical process that he borrowed from Hegel. He saw his own vision of capitalism, socialism, and communism as the logical results of dialectical materialism and not something in a Utopian vision. However, when critiquing Marx's ideas, one has to see some level of utopia present. Even if one concedes the idea that socialism will invert the structure so that the 99% own power, an idea that could be seen as Utopian in its own right, the point in which government "disappears" is a Utopian idea. Marx's argument is that since all conflicts are based on the ownership of the means of production, if this is publicly owned, there is no longer a discussion of such elements needed, therefore government is not needed. In its most basic form, there is a Utopian hope here. While I believe Marx would definitely reject this idea because of his absolute belief that his reasoning is rooted in rational analysis, there are some leaps of faith that one has to take, leaps that have been demonstrated with the passage of time that end up making some of the resolution elements of Marx's writing a bit on the Utopian side.
