That is a fair point. There, I agree with you, don't tell me I argue forever.
As for Tung Chung, my in-laws live there. Plane noise is a nuisance, but that issue aide, actual living environment is not really that bad. There are some nice parks (and by parks, I mean actual parks with green grass and trees) and tree-lined roads. The direct MTR line to Central means if you work there, then transportation is acceptable. Of course if you work in say Tai Po or Sai Kung, then, yeah it will be a hassle.
