I was historically a low mileage guy. I came to the sport late when I decided to walk on to my college team with no prior experience. Getting thrown into the rigors of a college program without any historical base and having a predisposition towards injuries because of structural issues (flat feet, bowed legs, hip issues) meant that I got injured pretty easily and often, even when my coach tried to bring me along slowly. I only cracked the 70 mile barrier three times in my life until age 42, all three coming during my junior year of college. As a steeple/5000m guy, I was able to get away with that because of some degree of natural talent, and I offset it some with smart and efficient training.
So if you are an inexperienced runner, or if you have a predisposition towards injuries, or if you live in a n inhospitable climate, or are an older runner, you may need to go low mileage, and that would not make you lazy.
The "ignoring the injuries" claims are silly. It definitely works with some injuries, but it is a terrible approach generally.
All of that being said, the more miles you can run while remaining healthy and not leaving yourself too tired to do your workouts properly, the better you will be as a runner. Since moving up to marathon training for the first time at age 42 and increasing my mileage as a result, I have run faster times at every distance than I have run since I was age 23 (although I did have some big gaps in my running in between). The miles made all of the difference in the world.
