Putting up a smoke screen can be a useful and necessary tactic, as long as it conceals something worthwhile.
Trying to hide vacuousness and/or so-called importance per se is not what it is all about.
Face the facts, put up the smoke screen as required, and make sure that the hidden concept is something needed in the near future.
There is no use in pretending, because when all that smoke rises and dissipates the truth will be revealed anyway.
Revealed truth is something to be reckoned with no matter what.
