> Rural living, outside those with careers in agriculture, is not scalable or sustainable.
I have no idea what you mean by this. Everyone outside of the city isn't a rancher or farmer. Ag is a huge industry with a lot of opportunity, but not the only game in town.
If you're talking about population density, we could easily double the number of people in my area with very little change in observable density. In the sq mile that I live there is only one other family.
Combine remote work with low property taxes and lower real estate values, living in a rural area is increasingly attractive and makes a hell of a lot of sense to those interested in that lifestyle.
