Whether the conclusion follows from the omission is in the eyes of the beholder.

That's implicitly declaring that there's no such thing as an objectively non-sequitur argument.

Not exactly. I'm declaring that "non-sequitir" does not apply to conclusions drawn from omissions.

However, a conclusion drawn from something said could indeed be a "non-sequitir" - for instance, "the coffee is ready" does not follow from "the bread is in the oven."
