And you’re still arguing from the conclusion that there needs to be a wall. There isn’t one in any other setting, even when there is an Asmodeous, and various other entities that want souls. The idea that refusing to worship anyone merits utter oblivion, in a setting where the gods are objectively not especially great, is just absurd.
You call it absurd, I call it entirely believable and actually functions to set Forgotten Realms apart from other settings. You said it yourself, there isn't any other setting that has a Wall of the Faithless. This is a particularly Forgotten Realms thing. Cool. FR needs stuff that sets it apart from other settings.
Strip out the wall and what? We've got another vanilla setting where if you do good deeds you go to your just reward? Whoopee. We already have a half dozen of those settings. What's the problem with letting Forgotten Realms actually be different.
It's actually kinda nice to see faith baked into a setting instead of just something tacked on if you happen to feel like it. Honestly, I think that more settings SHOULD be more distinct about what happens in the afterlife. Faith in Forgotten Realms MATTERS. Lack of faith in a patron diety matters. It's a BIG DEAL. Which nicely makes FR very different from other settings where, let's be honest, you could wrap yourself in tinfoil and jump up and down on hilltops crying all gawds are bastards and nothing happens.
