This is just a guess:

It seems likely to me that the Aldmeri Dominion see Tamriel as their rightful land. Keep in mind that Elves ruled Tamriel longggggggggg before Man ever set foot on her shores.

From a religious point of view, Talos is, technically, a mortal. Of the Nine Divines, Talos is the only one to have done nothing to contribute to Nirn's creation. The other Eight contributed greatly, almost killing themselves and sacrificing much of their power to create the planet. As such, and for Talos having been a human in life, rather than en Elf, it is reasonable that the Dominion would seek to destroy Man's institutions and return to the way things originally were.
