"In my lifetime, this has become existentially linked to a commercial orgy that has now even co-opted the ritual angle."
Perhaps you mean synonymous...NPR hosts, at least I've noticed because existential is a very important concept to me, sometimes use 'existentially' to perhaps sound more intellectual.
Ex: "Iraq's latest actions pose an existential threat to Israel." (A made up sentence but correct in the NPR usage.).
An existential threat to Israel means it would no longer be a 'jewish state'. Literally destroying the country, which is what I think is meant, wouldn't be existential...it would be real... really real... 'conventional'.
A person pointing a gun isn't posing an existential threat. A slanderous article about someone's gravitas is an existential threat.
