Why can't we declare classes as static in java ?

I am not talking about nested classes!

 static keyword marks a method or field existing independently of any instance of a class. A class exists once anyway so in effect, all classes are "static" in this way and all objects are instances of classes.

At a high level this question deals with the difference between objects and types. While there are many cars (objects), there is only one Car class (type). Declaring something as static means that you are operating in the "type" space. There is only one. The top-level class keyword already defines a type in the "type" space. As a result "public static class Car" is redundant.
