I agree completely. I always thought (and later dug into and pretty much confirmed) that people only theorize who the Beast Titan could be because they want some kind of thrill for a currently lacking arc. Nothing in the world to support any kind of claim, that's why I ended my post basically saying that the Beast Titan is something original and new.
