It’s simple emotional distancing. For many, talking about sad things makes them irrational or depressed, so if it has to be discussed it will be done so in academic terms.

The less conversant you are with the actual academia, the more contrived the terms you invent will be. I doubt many did more than undergrad business or economic here.

Sure, plenty of people do. Head down to the local bow tie store, or visit your nearest seasteading ship and you'll find that almost everyone talks this way. Just be careful not to violate the NAP or you'll be blown away by someone's rocket launcher.
