Not that long ago 10 acres on the north shore of Kauai was not particularly expensive. It has largely been developed in the last 20 years or so. My point is that the neighbor may not be particularly rich, especially if he is a farmer. It may be that he is more willing to accept a large estate, rather than a subdivision in what is a largely rural area. Note that I am in no way commenting on the situation Zuckerberg finds himself in, but there are people on the north shore who farm (own land/not rich).
