FFF
One of the attractions of grass roots flying is that pilots are responsible for their actions and don't want/need nannying. Pilots who aren't happy with that have loads of 'controlled' fields to fly from.
ATC is entirely appropriate for commercial, all-weather flying. At small felds like Barton it would kill the field's 'character', cripple the movement rate, make mega circuits mandatory iinstead of a crime (itself a safety issue), and spell the end for non-radio flying.
