How can I convince skeptical colleagues about the right namespaces in .NET?

My team is working on a conversion project to convert a single product (but with many faces) from VB6 to .Net (we have more than ~ 300,000 LOC). Before I went on board, it was decided that regardless of the location of the assembly or folder structure, all classes / structures will be in the same namespace:

.

They even go as far as modifying the developer code, developer code, developer code, etc., to ensure uniformity. How to convince them that using a namespace is good? What is the proper use of the namespace and what are the pros and cons? I guess it's hard for me to understand why my colleagues will go through so much trouble to save a few lines. Any external, authoritative links to support your argument will be highly appreciated. Please, help!

I read a lot of good answers (the image of the driver folder is good, for example, as a division / organization of an object / concept).
