You say that this (see beginning of #38) is the intent of "It is not like the land of Egypt"? Perhaps it is because the land of Egypt is the "refuse" of all the lands that Scripture contrasts it with Eretz Yisrael. It is, therefore, written (Bereshith 13:10) "like the garden of the L-rd, like the land of Egypt" — like the garden of the L-rd for trees; like the land of Egypt for seeds.
— But perhaps it is being contrasted with its most demeaning feature; it is, therefore, written (Vayikra 18:3) "in which you dwelt" — the place in which you dwelt, of which it is written (Ibid. 47:6) "In the best (part) of the land settle your father, etc." But perhaps it is being contrasted only with the time of its demeaning (i.e., its being smitten with the plagues). It is, therefore, written "from which you went out." When you were there, it was blessed because of you, but not now that you are not upon it.
