An interesting take on it, and one I agree ith mostly, with a couple of exceptions (but quite big ones in context of this 'narrative' ! lol).
Economy (transfer of energy from one place to another), and hierarchy are not social constructs.
They are natural rhythms that run throughout nature, and were here long before humans stood up on two feet..
So I agree with the perspective, but pretending that real things are constructs, only means that you staying within the matrix...
