If you mean to say that society is a construct, well, yes. You learn that in the 101 course.
That does not lead to a "this is bullshit" conclusion, unfortunately, because we act on the stories we tell ourselves.
There are different levels of "construct" though. There are historical documents from the middle ages, from Rome, from ancient Egypt, etc. that can be checked to a certain degree. And there are stories that are just made out of thin air about how humans supposedly lived 50k years ago. This is not all the same.
