One of the busiest gliding sites in Europe (Lasham) manages perfectly well without ATC
The civvy airfield that I'm a member of is air to ground. It has full runway lighting, PAPIs, VOR approach, snow clearance, is a biz jet hub for the north, operates two fixed wing and one rotary flying school and has hangars full of privately owned aircraft. I can count on one hand the number of times I've rejoined and there has been no circuit activity. If they can operate like that, why can't Syerston?
