It doesn't render them useless at all. Namespaces prevent name
collision. If you have two classes with the same name in different
namespaces, you can always disambiguate by using the full name, which
you couldn't do without namespaces. The "using" statement just allows
you to avoid typing the full name when there *aren't* any collisions.

What sort of problems? How often is this occurring? I ask because I
only run into it once in a blue moon...

I think you'll find you either change your mind quickly, or if you're
working with others they'll petition you to change your mind. There's a
good reason why basically no-one does this.
