Your unease is more warranted for things like evolution, which does not depend on a shared imaginary space.
Where did you get that from GP's post? They're simplying saying not to anthropomorphise societal systems.
Maybe you wouldn’t consider it a real society if they depended on machine translation, but we’re partially there already. It would still be a collection of minds with their own identities and intentions coordinating through an abstraction.
"X does Y" implies nothing of the sort.
If I say "The River Flows" am I arguing that the river is intelligent?
No, absolutely not, you've setup a strawman from the very beginning.
"The police are only there for ... " does not imply there's some overlord with a power point document with a bullet point outlining what the police are there for.
For specific examples here like, “the police are not there to help you, only the rich,” you can easily find counterexamples, but let’s be a little more generous and imagine it means that the individual intentions of officers are negated by something else. That something else is more likely to be the interests of real living people and not abstract institutional purposes for which the police were created. The institution might provide them an opportunity to pursue their goals because of the power it presents, but any misalignment of goals with public interest is because of the intentions of people in the system, not the will of the system itself.
Maybe that seems too obvious, but I think it’s established that people tend to anthropomorphize things, and when we talk about the will of the police or the state or a corporation, it’s easy to slip into thinking of an abstract entity as a person with thoughts and desires, which only hides the problem.
This was usually based on the further misunderstanding that evolution represents a progression from lower to higher life forms. For example, Engels was especially influenced by the idea that political processes followed Darwinian principles and that societies inevitably move from lower to higher forms, leading toward perfection in communism. In the U.S.S.R., science fiction assumed that aliens would all be Marxists because it was a fundamental law of the universe.
Even in the case of evolution, there are minds with intentions. Our ancestors wanted certain things, and the ones who were able to get them passed on their programming to the next generations.
