So lets say you had a small-ish farm, run by two siblings and partly owned by the rest of the extented family OTL (due to inheritance machinations). How would that work ITTL? What about if a farm manager was hired? Would Butterflies stop such a thing in the first place?
The 'use it or lose it' regulations were specifically targeted at large landowners (and more specifically at the absentee Protestant Ascendancy in Ireland) so I think it would be unlikely to catch this kind of situation as such. There definitely will be some farmers who appreciate the value of remaining small and won't have joined cooperatives.
