But once your code gets big the disciple of using classes helps

Even before your code gets big, discipline helps maintenance. :-)
Every level of your program has globals. An application with too many
classes is no better (or worse) than a class with too many methods, or a
module with too many functions. Insert your own definitions of (and
tolerances for) "too many," which will vary in flexibility.
I think the need of classes comes when you need objects thus a set of
variables with an identity and that may be created N times. Classes are
object factories.
A second aspect is inheritance: classes may inherit from other classes
and reuse existing functionality and data structures for their objects.
In cases where you only need to encapsulate a single set of data and
functions modules are the best choice.
