An actual Esperanto speaker here. I need to correct this. It was never intended to be a "diplomatic" language, as such a language only spoken by diplomats between their kind. So the language of a small elite, which does not want to deal with the average man on the street. That sounds like a story which was said about the predecessor of Esperanto: Volapük.
Esperanto was at some point in time the "workers latin", because the less educated worker could learn it as a means to talk with people from other nations. That ended with pushing English or other "more practical languages" in schools to this day.
Esperanto still is a working living language with a working worldwide community.
