I am not sure what your counterargument is. But in mathematics and computation, people have tried for at least 150 years to move away from natural language, and figure out stable foundations that can be externalized. I think there is a good reason for that - you save time correcting errors due to different interpretation.

We are in fact finding out precisely why natural language sucks in real time, as we have all kinds of catastrophic errors with people who think this is finally the time for complex language to prevail over pesky nerd language. The only difference is that more people seem to prescribe to the "you're holding it wrong" handwave when said catastrophes are pointed out.

Extraneous and ambiguous is superior? Or are you talking about hypothetical new spoken languages?
