The realm collapses into several kingdoms like it should have after the dragons died
I don't think the realm would outright collapse into warring kingdoms, but something like the Magna Carta would've been forced upon the Targaryens by the nobles after the Dance of Dragons. A combination of dragons devastating the land and the Targaryens losing their medieval F-16s would make the crown hated and weak, enough for the nobles to force certain laws and limits upon the crown.
This is probably the biggest flaw in ASOIAF with it's depiction of religion. You're telling me the only religious people are fools like Baelor The Blessed? Give me a break.
In the actual history of Europe, you had religious kings like France's Louis IX and Austria's Maria Theresa who were good bureaucrats. You had religious kings like Philip II of Spain who was like what if Stannis was actually religious and actually became king, because he was a hard, puritanical absolutist who insisted on his right to rule and sought to defend his domain at all costs, even if it meant burning people at the stake. You had religious kings like Ivan IV of Russia who started a reign of terror, but quietly sent a list of names of people he murdered, directing the priests to pray for their souls. You had religious kings like Philip II of France who built up the royal state to be effective and acted as the military arm of Pope Innocent III.
You had state-builders, you had bureaucrats, you had absolutists and even dudes who launched terror campaigns, and the only religious king GRRM can come up with is a flower-boy hippie who thinks sex is of the devil. My ass. It goes against Medieval theology where the natural, material world is seen as a good thing, because God created it, to the point where they burned a religious denomination at the stake for seeing the material world as evil. Not to mention that people, even in the Church, will start asking questions if you don't pleasure your wife. So no, someone like Baelor the Blessed would be seen as a weirdo, even if he were to be a Catholic instead of a follower of the Faith of the Seven.
GRRM will never write another Dunk and Egg story which will fully and completely confirm the fact that he doesn't want to write anymore and isn't capable of writing.
TWOW is impossible to write because last two books are terrible slop, but he can't write Dunk and Egg either because he is a lazy cunt.
That's the problem. Game of Thrones spiraled into stupidity after they ran out of book material that wasn't needlessly convoluted slop. AKOTSK might run into a similar problem once the third season is over. Unless GRRM himself takes over to write the scripts for it, which is what he should've done with Game of Thrones and House of the Dragon.
