As someone who has debated the topic several times and have done an analyze on the subject (and planning to do another one), I could give a sleu of reasons against it.

I'm short on time right now so I'll just give the tl;dr version:

The theory requires jumps in conclusions based on very little evidence. It cherry-picked lines of narration that have to be interpreted in just the right way to mean anything which makes unbelievably convoluted. I doubt Toby Fox would hide that Chara was the narrator in a line like "The dog food bag is half empty" (because that's kind of asining way and confusing way to show it's Chara).

Worse it ignores other narration that contradicts the theory. Like Chara speaks in full stop sentences and first person while the narrator doesn't. Which if anything shows that Toby indended to them be different (otherwise why give Chara a specific speech pattern).

Generally a lot of it relies on headcanon without explaining how they know that is the case. For one, Chara wouldn't know what Asriels attacks are. This is a new form and he's never taken it before. Yet this explained away by saying this is a character he invented as a child, even though there's no indictation (plus "god of hyper-death" is title specific to this situation).

I expland upon this more later.
