I think what you describe is preferable and is how I like to code in general, but then I find that the complexity comes from how these things communicate. It's not actually true in general that the whole is greater than the sum of the parts, but it's good to have a system that possess this property.

But that complexity is even larger without this encapsulation into components. Reducing the complexity by reducing the potential communications surface is a large part of the point.
