No building type or construction method is without its drawbacks, and you are right in pointing out those of earth sheltered design. However, as you also point out, these factors can be reduced or eliminated altogether with good design. That said, I think it's self-evident that any structure, above grade or below, always works better when designed properly in the first place. Who would do otherwise?
The problem of Radon gas is a problem for houses constructed above grade, as well as below grade. With proper ventilation, though, that hazard is reduced or eliminated. Also, a thorough analysis of soil composition done prior to design and construction can aid in determining whether or not Radon is goign to be a problem or not. Not every site has sufficient quantities of uranium in the soil to make them a Radon hazard.
As for the water table issue, naturally you wouldn't build in an area with a high water table. This is one reason why I said to the guy who posted the original message in this thread that building all underground buildings everywhere is a bit over the top. Granted, earth sheltered buildings have advantages, but a world with nothing but earth sheltered buildings is pure fantasy.
