So what have RPGers been doing these many decades? Kidding themselves?

Again, this is determined by the world. There is no such thing as GM authority or Player authority. I've explained in the above two posts.
These are very shoddy game mechanics when used in an RPG. They force players to think out of character and "game the system". They are antithetical to roleplaying because they cannot be used while roleplaying.
As I've said before neither the Players nor GM have authority. If this is the same as narrative control, then the same holds true. If you are saying, "who gets to determine what the PCs do?" That's easy. Each PC decides for his or her self. You act in character. Sometimes its hard (as anyone reading here can attest as frequent roleplayers), because PCs don't always want to do what we the players want to when playing the game.
I again actually disagree with most of what you just said.
First off the World is actually the result of the "official" rules of the system, GM authority and player authority. By itself it does not exist. It cannot react, it cannot do anything. It is just a shared imagination space.
For all intents and purposes it does not exist except as the result of GM authority, Player authority or the rules system. To me this seem very obvious but there must be some disconnect between us.
If I as a player decide to burn down a building. What tells me whether the house burns down and whether some nearby buildings also burn down.
Either there are detailed rules sets that say if you roll a die using skilll A and equipment B and get this number a building of size X of material Y will burn down. Maybe the rules are so detailed they can say that other buildings within Z distance made of material Y have a % chance of also burning down.
Very few games have this level of granularity with the rules.
So what are the other options to decide what happens.
The GM says. That sounds reasonable based on my experience so he says that putting a torch to the building will burn it down. This is GM authority.
The Player could say well I want to burn down this building and if I make this roll (luck roll doesnt matter) or spend a drama point etc. I get to say whether the building burns down and whether other nearby buildings burn down.
The WORLD doesnt get a say in the matter it is a product of the above three entities. The world is not real, it does not exist. It is the end result of the rules, GM and players narrative control.
Now many times GMs and Players base the world on our world and then add some additional details (say magic). But that is because it is easiest to do it that way as it puts all players on the same page. But manytimes the world due to even system rules does not work like our world (say falling damage) or for instance. Sometimes the ruleset is overridden by GM (or player authority).
You will have to explain how the world can do or react or determine anything cuz right now I just dont see it.
