The more interesting question is why doesn't 'nix have Powershell and a layer of abstraction upon which it can sit equivalent to the CLR?
Perhaps to be files all the way up is a limitation of the bazaar - at least until one hits the JVM, hopefully. There's no contract assuring that level of abstraction between the user and the turtles. And agreement that such a layer of abstraction is a good thing is unlikely to be forthcoming.
