The real structure of capitalism differs radically from the way it appears to function. If one word could substitute for the complicated metaphors used above, it would be on par with these concepts. In other words, we give up the idiosyncrasies of invention for the economy of language held in common. Private abstractions are replaced with a public abstraction we agree upon. The standardization this entails brings an added benefit.
Words have a history.
The same could be said for a metaphor, of course, but the process is much more distinct in the case of a single word. When leftists do forego specialized language for the sake of winning a larger audience, they are faced with a dilemma. Where I come from, when you respect someone, you hold them to the same standards you hold yourself to. If leftists indulge in anti-intellectualism of this sort, they are actually asserting their intellectual superiority over ordinary individuals with whom they claim to be equal. The difficult part is deciding when an argument is too hard for the people it is trying to reach.
