Maybe I'm reading this wrong, but it seems like you're implying that
procedural code is inherently unmodular. Why would just one class/instance
suffice to represent a procedural program? I think of namespacing and code
organization as broad concepts that cut across all styles of programming.

Interestingly, Python's main unit of modularity is the "module", not the
"class". A direct translation of a typical Python module to Java would look
something like a Java class containing only static methods and inner classes.
Even this would be considered rebellious within the context of ordinary Java
programming.
