You're missing the point here. Learning another language is not only a means of communication but also another way of thinking. For technical purposes it makes no distinction, that's for sure, but the moment you step outside that bare-bones use you will start missing increasingly more and more. I'm a native spanish speaker and I can not imagine my existence not understanding english from heart. Translations can't get anywhere close. So that much, that many translated movies have some lines directly changed to a completely different meaning because the original english one makes absolutely no sense regardless of reformulation, or might even sound hopelessly dumb.
