I would think the bigger debate is merging programs through consolidation, such as the idiocy of two tiny schools in Fulton County continuing to field separate football teams and barely have enough players some years. Otherwise, the reasons to permanently end it would be:

Size/enrollment
Revenue/funding/costs (operations, insurance, equipment and facilities.)
Compliance violations

On the field success or failure should have little to do with it, but consistent failure and or lack of competitiveness is a symptom of another problem. You could also make an inverse argument about what is preventing the start of programs in the counties that don't have football.
