Generally speaking, about 2-5 acres is enough. Most rural build to suit lots are in this range. A square mile is a ludicrous amount of land and not at all typical for rural living. If you have that much land, you're a farmer, have had it given to you, a significant portion is unuseable, there's a large pond/lake on the property, or you're just eccentric. Even out in the country, there's an amount that's practical and beyond that is just a waste. Once you get over 30 acres, it really starts to become silly.
