I wouldn't worry about the dirt he took, think of it as payment for his time and expense to widen the road and make it safer.
Looking at your pictures again I see a turn/curve in the road not far from where he was working, and there should be a lot more trees removed and the road widened for safety. If you don't want him doing it, then do it yourself.

Man that reminds me of some of the old township roads around here, just hope you didn't meet someone coming the other way going around a turn and when you did just hope you could get stopped or there was just enough room to pass.
