What do you mean?
We've seen countless world systems and types of economies. How can one posit that one of those types are at odds with biology?
Biology because communism, as I understand it, necessitates the partial or total erasure of tribalism, which is innate. As animals, we weren't built to organize beyond the tribal level, it's only through our intellectual faculties that we managed to. But even then, tribalism cannot be completely erased. Were civilization to collapse tomorrow, tribalism would endure, and would be the default mode of governance until we recover/rediscover the more complex systems.
Economics because communism is not competitive. In a classless society there would be a reduced drive to "get ahead", because there would be no state of "ahead" to reach. Now, this is not a problem per se, but any "true" modern communist society, would be surrounded by capitalists. I'm not sure how they can survive it, in the long term.
Capitalism accounts for both. It assumes, broadly, that whether the scale is the individual or the tribe or the nation, that they will look out for their own interests before that of others, and it is this interplay of interests, the competition, that gives rise to capitalism. Even if communism can work within a homogenous tribe, there's no guarantee it can reach across tribal boundaries. Doing so requires a fundamental change in how humans think.
Furthermore, there are no guards against the creation of a privileged class within a communist society. Let's say, tomorrow we revolutionize the world. All the 1% have been divested of their assets and the process of redistribution has begun. Who handles it? Probably those who are experienced in administration. What's to stop them from becoming the de facto elite, because they control the flow of goods? Going another step, the redistribution was successful. Class has been abolished. What's to stop the rise of a demagogue through sheer talent and/or charisma?
My grasp of economics and politics are both amateurish, but I just don't see it. Hierarchy is the "natural" state of civilization. By "natural" I don't mean "ordained by nature", but that, like certain isotopes of atoms, it's the most stable for a broad range of environments. There must be a reason most primitive societies invented trade, while few societies managed to remain communistic, without any concept of property.
