If you say "mode of production," that sounds as if you're refering to a physical mechanism. terms like "feudalism" or "slavery" are sociological terms, not descriptions of physical mechanisms for producing value and in all thier iterations, value is produced the same way. When debating sociology, people can argue for or against capitalism on many grounds, however when looking beyond semantics and sociology to the actual mathematical function of capitalism, we find it has absolutely zero legitimacy as an economic system.
