You make a good point.
On the other hand, I have hunting rifles that will shoot around .5" at 100 yds. Is that necessary? No. However, I have found it increases my confidence 100x to know that I can shoot for the left ventricle or the right ventricle. "Aim small, miss small" has a whole other meaning when your weapon shoots bugholes and good glass is needed for that.
I admit it's easier to get fussy when you have a few bucks and you'll have to edit out what doesn't work for you. For many, many years I owned a Savage .270 with a K2.5 Weaver scope and used it to good effect on many critters.
