As far as languages go, there needs to be a balance struck between things being clearly ordered and the need for things to be loose and flexible. An as Jordan Peterson pointed out, the personality traits of order vs flexibility seems to be something that differentiate "Liberals" and Conservatives on the political spectrum, the former generally wanting more flexibility and the latter wanting more order. This applies to language as well (and political words are particularly bad on this). Take the word "Libertarian", there's a significant amount of people who thinks this term has so broad a scope it can be used to define people with polar opposite values, and if you try to clearly define the word, they will berate you for not being "inclusive" enough. Which is obviously ridiculous, because if a word is so watered down it can be used to define anything, it defines nothing, and essentially is of no use as a word anymore. Thus you must actively fight against sloppy language use in which words are used to mean things they're not supposed to and thus their meaning expanded, as this sloppy language use is what contributes to the watering down of the language. Because English is the most widely used language, being used all over the world in a lot of different cultures and environments, it's probably been subject to this process of having meanings and definitions watered down and expanded upon more so than languages used by small, culturally homogenous populations, which brings the benefit of having an expanded vocabulary but with the downside of added vagueness. I'd imagine German is precise and functional because that's the character of the German people, but I don't think you can just reproduce that functionality by copying their language, because that functionality essentially stems from the people, and if non-Germans were to use the language they would probably degrade in to something less precise over time.
But in example of Aurani here, it was definitely his fault for misusing the word "functionality".
