I do. Because most people will never use their 4wd. It's just like people who buy hummers and use them to pick up groceries. I work in construction, and my 2wd work truck has been in plenty of mud, more than the average persons personal vehicle would. It hasn't let me down yet.
I do see the need for 4wd, but for a lot of people it is unnecessary since they'll never use it. A lot of them won't even take their truck/suv out in the snow because their scared.
