What makes it worthwhile, that it exists. Is it only of primordial essentiality that differentiates between the words that we have, with reference to a narrower context? Perhaps so.
We can’t live without Jargon. Jargon has become so tied all our special lives. We’ve created special zones that need to be jargoned and the jargon and lingo-specific words keep getting invented. There won’t be a end, because mixing and matching will continue till eternity of human language.
It’s an issue of creatively putting together words. How the meaning changes and are made to change, sometimes the formed words/ lingo coming to represent a combination or the sum-total of all words involved or a totally different meaning, altogether.
