I think you are looking too deeply into this.
Not quite sure of your take here, by I agree with Gringg's skepticism. Perhaps you should switch your "waders" for a deep-sea diving suit and see what you discover.
Even the WTS paints a picture of a "tract-home" paradise:
True Peace and Security - From What Source
chap. 9 p. 108 Peace and Security Earth Wide—A Reliable HopeThose alive today, therefore, represent a sizable portion of the total that has ever lived on earth. In fact, in 1966 it was stated: "It is now estimated that 25 per cent of all the people who have ever lived are alive today." 35 On this basis the total population throughout all human history could be estimated at some 14,000,000,000 persons. The earth’s land area is more than 36,000,000,000 acres. That would allow more than two and a half acres per person. Not only would this provide space for food production, but also it would allow for forests, mountains and so forth with no undue crowding in the paradise earth. Then, too, it must be remembered that the Bible shows that by no means all those now living will survive and live in that new order.
That 2.5 acre parcel does not account for mountains or unbuildable land (for construction purposes). Also the WTS estimate of 14 billion dead is very light. My estimate is actually 1.5 acres per person.
But even if you accept the WTS numbers, that means your piece of land for house and farm would measure about 520 feet on each side. Compare that to any picture in the publications.
