A counter-argument on that could be made. The Argonian Account clearly mentions that humans could even travel there.

Also, there is far more that just Argonians that lived in Black Marsh. It was the Khanaten Flu that supposedly killed the Lilmolith & other races in Black Marsh.

Many more arguments can prove that more than just Argonians can live in Black Marsh. It is a grossly misunderstood place. Assumptions should not rule the possiblity out.

So, perhaps non-Argonians just need to prepare themselves in some unknown way, or are just naturally tough. So, there are probably a few other races outside Argonians in Argonia, though they are probably well hidden  ( maybe hidden people's exist elsewhere, ex : Akavir ).
