"My point is simply that someone like mark twain is able to bend otherwise poor grammar to fit a number of ends."
Mark Twain was a master of the English language. We shouldn't confuse his characters' "poor grammar" with his. Huck Finn talks like a redneck because Huck Finn is a redneck. That's not Mark Twain's voice; that's his character's voice.
By contrast, read an essay by Mark Twain. The language and style are markedly different from those of his novels. Sure, there are some allowances for colloquialisms. But those are stylistic choices, not failings to grasp the mechanics of grammar or syntax.
"you can convey some types of subtext though gibberish more cleanly than you can with perfect prose."
It's not about perfect prose; it's about clarity and economy of communication. There's no such thing as "perfect" prose, anyhow. But there are such things as clumsy prose and clear prose, or correct syntax and incorrect syntax. Generally speaking, it's preferable to be on the latter end of those spectra unless writing for particular effect.
