I'm not sure you understand what modularity is all about. There's ample evidence that Functional Programming (esp. with immutable data) gives you a lot of aspects of a 'module' for free. Any function programming language can describe and enforce module boundaries. Some mostly at run-time, but that is A-Ok in my book. I also find it funny you mentioned "large monolithic state" when most enterprise apps try to hide that fact that all your data is in a database (the large monolithic state), by stashing it into objects through some magic ORM...
