Capitalism, with all of its imperfections, is a system that can more easily feed billions of people than the many systems of social organization humans have created. One of the most important characteristics of Capitalism is the system's facility to manage and respond to input from many sources. The more connections the more powerful and efficient the system can be. And in this context, Capitalism depends upon the computing power of human brains to act in connection, via "common narratives" (Harari, 2017,) to produce decisions that single and small groups of people cannot achieve based upon their limitations of connectivity and processing power. Thus, Capitalism, for most of its history, is a social system. More critically, Capitalism is not a mature system as Marx observes; however, since 2007, technology offers (see Friedman 2017) a platform upon which Capitalism may mature from a biological social system into the purer form you describe. The invention of no-trust systems coupled with the connectivity of cloud services, artificial intelligence will be able to scale up to unimaginable dimensions and perform far more efficiently than what we have traditionally called the market. In essence, biological emotional distributed computing is being replaced by nonhuman algorithms that can more accurately forecast the market than human feelings can respond to the market. The plurality of human input in terms of emotions of fear, greed, and the desire to create, that was the market, transforms into a system of efficiency that could support the human creativity, while creating enough goods and services providing humans with, not only their needs, but with everything humans believe they desire. The oligarchic functions of premature communism of the past is taken on by a more competent tyrant: the algorithm. Perhaps, what Marx fail to appreciate is the true nature of alienation: the separation of humans from trivial, repetitive, non-creative toil, which I believe is our future. Steemit is one of the first steps in this direction.
