That said, even without Marx talking shit (which, let's be honest, was how he made a name for himself among his contemporaries, let alone now), your point regarding a shift in the sociotechnical realities (this to be distinguished from sociotechnical imaginaries, in accordance with what follows below) of the past two centuries still stands.
We do not live in 19th century Europe. The material realities of our present history are markedly different. Heck, the material realities of 19th century Usia were markedly different than those of 19th century Europe. Yet our social theory wants to be ahistorical and to transcend social geography, to be a univocal commentary on naturalized power relations.
This being a monological commitment that even Marx couldn't sustain. Hence his having stuck Grundrisse in a drawer rather than publish. Having identified communal ownership and communal management of resources in medieval societies, he decided to just not talk about those exceptions to his grand theory of history.
Best not confuse the cause with facts.
Yet it is facts that define the territory our Korzybskian maps would help us navigate. When facts on the ground change, such as transformations of how we enact and are enacted by medicine (cf. Mol), this reterritorializes our lived experiences. We can't keep navigating with a Rand-McNally road atlas from the other side of two centuries.
