Even though the emergency status gives priority, it does not
create a magic wand that eliminates the traffic.

It is not a magic wand. It is respecting the PIC's needs expressed
with, or subsequent to, a declaration of emergency.

Had the collective ATC folks involved worked on getting the requested
runway available as they should have, then traffic would have had to be
handled as necessary.

Perhaps, in turn, that could have created other fuel emergencies
(although I doubt it). If that had been the case,then perhaps in turn
that would show that AAL and others have conned a weak FAA into letting
them cut back their dispatched reserve fuel requirements far too much.
