I think you outline the down side of rural/wilderness living quite well. As a career National Park Service employee (retired) I am familiar with much of what you discuss. Either I have experienced it, or lived and worked with families that have. The negative effects of wilderness living are much more significant for children than for adults.

The better solutions involve situations where you can transition from urban to wilderness with ease. Even then, nothing is perfect. I was rudely shaken awake on San Miguel Island (as raw and screaming a wilderness as one could hope for) and spent a restless day wondering about the situation of my wife and daughter back on the mainland, to say nothing of friends and associates back on the mainland. My daughter grew up with the advantages of participating in a well functioning educational system but also many experiences in the northern Channel Islands helping dear old dad with the chores.
