Yeah, but as I showed, there's already tons of redundancies in D&D. If you want to get rid of the redundancies, then honestly the best thing to do would be to make a brand new setting that doesn't include them. If people are saying that gods and arch-fiends aren't redundant, it's because in their games, they're not. But in D&D as a whole, they're no more (or less) redundant than anything else.
Pause. My entire argument is about whether or not they are redundant in the official game. I personally have done other things, but my argument is not about what I have done. My argument is solely to demonstrate the redundancy.
So let's say we get rid of either arch-fiends or evil gods. What are we losing? From a purely mechanical standpoint, not much, by RAW.
This is my argument.
But from a storytelling perspective, there's a lot that could be lost. Whether you homebrew a mechanical difference or just say it's purely a social issue, there's interesting stories that can be told. What if Asmodeus wants to be considered a god because that's more "legitimate" (in some beings' eyes) than being an arch-fiend? I can see mortal societies tolerating or even accepting temples to Bane but being against an arch-fiend's cult. The stories of the gods tend to play out more on the Prime than those of arch-things, which means that there are more hooks for players who don't have plane-hopping abilities. In earlier posts, you said it was bizarre to have a god of murder, a god of envy, and a god of sin. But there's stories to be told there, where one of those gods (or arch-fiends) wants to have its portfolio expand to encompass additional concepts. I
If those aren't stories you want to explore, that's totally fine. But it shows that what looks like redundancy doesn't have to be.
But from a storytelling perspective we can also have stories where the Demon Lords are older and more powerful than the Gods, and the universe is a dark place where the light is under constant threat. Or any number of other things that rely on not being redundant.
The storytelling works both ways.
As for the my earlier point about sin, yes it is bizarre and I don't think that "additional concepts" is the way to even begin understanding my point.
The idea of Sin is that a sin is breaking a divine law, going against the will of the gods. Murder is a sin, right? Well, if you have a god of Murder, whose Divine Law is "commit murder" then murder cannot be a sin, because it is not against divine law. And considering how many gods of various "sins" or who can be easily attached to various "sins" exist in the setting of FR where supposedly Asmodeus is the God of Sin... it is a fairly empty title. You cannot sin if there exists a god who says that action is divinely supported.
