If it's VMC, and if the VFR departures are approved. If it's IFR, and there's radar service available, a tower can handle departures and arrivals much quicker. What's the most aircraft you've had in a hold, awaiting approach clearance? I've seen 4-5 in YTH, I've heard YXJ can get far more than that. If you get a tower and radar, that can pretty much go away, or be minimized, anyway. Having two staff in a tower, on doing air and the other doing ground also substantially increases the number of aircraft that can be handled by the airport safel. Phrasology differences, and the fact that towers have positive control also reduce frequency congestion.
As for flight schools boosting numbers: I don't have any experience working/flying at YAV, or anywhere else with a school, but most of the guys at flight schools (instructors included) are going to be far less experienced than even the lowest time pilot at an actual airline. Which would mean more r/t, poorer position reports, requesting things they don't want or need, and more incidents for busted clearances, runway incursions, etc. Locals might be easy to deal with, even in fairly large numbers. But when you add in alot of itinerant traffic, inexperienced pilots, and other garbage, it becomes much different. There may be a tower or two that could safely run as a very busy FSS, or busy FSS sites which would be far better as towers, but I wouldn't be too quick to say that you can do someone else's job when you have no experience managing the level and complexity of the traffic involved, and don't know any local factors that may influence it. Maybe YAV, or other airports could be switched to FSS. Maybe YAV might not require at tower if it wasn't close to YWG. Maybe it needs an upgrade to the staffing level to operate more safely. I don't know. But I'd bet that the controllers at YWG ACC, and pilots who fly in the area do, or at least they know far better than you or I (and some of each have posted in this thread). As others have said in here, FSS has its place (I know, I am one), but we're not controllers, and we're not able to handle the traffic that a VFR tower can.
