The only time taikyoku do matter is in a battle for the throne, unless you are fighting hajun then yeah taikyoku matter due to the sheer difference.
But we are actually saying the same thing aside from them wanting 1A singularity.
There is a hierarchy, and a transcendent one at that, a lower God would never reach a higher one due to clashing of laws, you will just keep falling through the layers of the singularity endlessly and never reach the throne room.
And soujiro and shiori could open Cajun singularly due to their nature, they did not clash with hajun head on, but that does not mean hajun does not transcend them, as when they got to the throne they were one shotted by hajun and also frozen and could not move
Send me the translation of the morei example
This would be a bigger downgrade, unless there are scans that the higher dimensions a we disconnected from the world
