And noise itself is actually "measurement error" at the receiver, which= is rarely Gaussian, in fact it really is quite predictable and/or removable.

Noise in the Shannon sense i= s random and therefore not predictable or correlated. Interference can be both predictable and correlated, and therefore can sometimes be removed / to an extent. Modelling interference as noise means not exploiting its inherent properties, and yes that means ending lower capacity.

"ending up with lower capacity"
