Personally my brain has an easier time grasping {TaskA(); TaskB(); TaskC();} rather than a 750loc block of code. Yes, multiple source files are annoying, but there's plenty of tools out there to help (ctags and vim is enough for me).

But the more important reasons to strive for high cohesion/low coupling are: Future changes are generally easier when you have well defined blocks instead of a birds nest of code, unit testing practically writes itself, and you have a better chance at isolating a problem to a module if it's responsibilities are few and well defined.
