Well, although that may be true for you, there are lots of Cessna 182's
that make
a lot of instrument approaches at airports with control towers. Or, even
instrument approaches at airports without control towers; all supported
by center
equipment, controllers, FAA approach designers, expensive flight
inspections,
etc., etc.

All of which would have been done whether or not those C-182's flew
those approaches. iow - no extra costs were incurred because of
those approaches.

Well....that is true for the cost of the center building. It isn't necessarily
true where an approach control serves what is primarily a general aviation
airport. And, it certainly isn't true for instrument approach procedures
established for airports that have no commercial traffic (which is many, many
more instrument approach procedures than those established for airports with
mostly, or some, commercial operations.
