What you are describing as performative I would describe as bureaucratic.
The Iron Law or Bureaucracy:
Pournelle's Iron Law of Bureaucracy states that in any bureaucratic organization there will be two kinds of people: First, there will be those who are devoted to the goals of the organization. Examples are dedicated classroom teachers in an educational bureaucracy, many of the engineers and launch technicians and scientists at NASA, even some agricultural scientists and advisors in the former Soviet Union collective farming administration. Secondly, there will be those dedicated to the organization itself. Examples are many of the administrators in the education system, many professors of education, many teachers union officials, much of the NASA headquarters staff, etc. The Iron Law states that in every case the second group will gain and keep control of the organization. It will write the rules, and control promotions within the organization. (Quoted from Wikipedia)
Makes me think of this timeless and excellent quote by Oscar Wilde:
“The bureaucracy is expanding to meet the needs of the expanding bureaucracy.”
Unfortunately, real-world bureaucratic orgs of any meaningful size or age always include a third type of person - dedicated neither to the org's goals, nor to the org itself.
In general, one should speak more circumspectly about that third type.
Yeah, pretty much all systems of governance ultimately evolve until their primary purpose is actually ensuring the survival of the system of governance and anything else it accomplishes is kind of a side effect. It's probably some sort of informational axiom of rules systems in general whether bureaucratic or biological or whatever.
Hell, DNA is just rules about what you can build and it's primary purpose is just making sure the rules survive. All the wonderful complexity and diversity of life is a side effect of the little changes necessary to propagate the rules.
