Social status is an example of a 'language game', or a 'consensus construct'. You can claim such things are not real, but then you need some way to account for their effects.
The motivating example of a language game is a language. Is English real? Well, it exists only because people use it. It is a thing only because of its effects, and not because it has any other objective status. It is a set of rules with power. Clearly it has no power over speakers of some other language (on some other planet?) that have not encountered the English-speaking world. But that does not remove the reality that it has for us, as people who are currently using it to communicate.
Social status, had in various ways, has power over people. It gets them to do something and not something else, to respond to some demands and not others. The fact that some folks don't acknowledge the same ways of attaining or holding status is like the analogy with language.
Not all rules apply everywhere. "Down" is not a thing in space, which does not remove the reality that it has for us. To claim that 'down' means nothing attempts to ignore the power the concept has when it does apply.
