I think several considerations should be factored in - and Minnesota DNR probably already has. In my home state of Arkansas - we have a statewide 3 pt antler restriction - on one side (except in the CWD area) - and a scope is most helpful when trying to determine if a deer is legal or not based upon how many points it is carrying. In addition, most states have a fairly healthy deer population - and most state Biologists are more worried about not killing enough deer than they are too many deer. A scoped weapon allows for higher harvest rates. I am not aware of laws that require a person to use a scope if they don't want to.
