I'm not sure how to give "evidence" that something is desirable. 
Something is desirable if people desire it. Clearly, you do not desire it, but I do.

You present the problem or friction you're trying to address, and then you demonstrate why your proposed solution solves the problem or alleviates the friction.

At the moment, I don't even understand what you're trying to accomplish. There are no examples in the paper to help me understand this, and the extent of the proposal is the single sentence "This paper proposes to allow the establishment of namespace scopes in an export-declaration and define a syntax
for doing so." -- and I'm not sure what that means.

Genuine question here, what do you want me to say?
I want this for the reasons I listed. To not have to wrap implementation files in namespace blocks, and to be able to simply and clearly declare a namespace. Out of the three main projects I work on, all of them have different ways of handling the namespace issue, none of which are satisfactory, to me or the authors. 

This is a good thing for the language, in my opinion, because of the reasons I listed. It solves the issue of how to export namespaces in a way that is compact, clear, simple and works well in several situations.

There are no reasons listed. What is "the namespace issue"? And in what way is the existing solution of how to export namespaces not compact?  

These are all the sorts of things that the paper should address.
