Sure, but to use the fallacy of slippery slope... where does it end? "Well, this airport doesn't serve commercial traffic, so it's not much of a loss."
Even if it is only usable by piston singles, numerically that makes up the huge majority of GA. If it were in prime real-estate it was likely a pretty convenient airport to use to access the community. I'd like to see the numbers of how much the airport was used and how many based aircraft there were before I judge that it wasn't much of a loss. If one or no planes were based there, then sure it probably operated much like a farmer's field would and didn't serve the aviation community as a whole. It very well could have had hundreds of operations a week in training traffic though, in which case it would be a great loss especially if it was used for short field training. Nothing better than the real thing to train pilots without a huge margin of error.
