So why does Ganon want to conquer Hyrule?
Here's the simple answer: He doesn't. Ganon is never said to care specifically about Hyrule - he just wants to rule the world. The exception is TWW, in which he had personal motivations, but that does not aid your theory.
Let's make a list:
LoZ: Ganon's motives are largely unknown, but he seems chiefly interested in the Triforces - they were the reason he attacked Hyrule, and also why he kidnapped Zelda.
AoL: Ganon is dead...
ALttP: Ganon wants to rule the world; his expressed wish is to "rule the cosmos" and to "conquer both light and dark worlds." Where's Hyrule on that wish list of his? I dunno.
OoT: Ganondorf wants to rule Hyrule? "No, the entire world!" - Zelda
The reason he stays in Hyrule is because 1) That's where his makai is, and 2) that's where the missing Triforce pieces that would enable him to conquer the world are.
OoX: Ganon wants to destroy everything. A bit simple-minded, isn't he?
FSA: Ganon seeks... Power? To rule (and ruin) the world? Well, that's what the inscription says...
TP: Ganondorf wants to merge light and shadow, create a world of darkness, and pretty much rule the world.
So, where's the quest for Hyrule in all of this? I really can't see it.
As far as TP is concerned, the Sacred Realm does not exist. It had no mention in relation to TP's story and no relation to the Triforce or the Temple of Time.
No, see, the Sacred Realm IS Hyrule. This is nothing new; the whole land just hasn't been given that name before.
You just made that up.
And for the record, Lanayru did not say that the people sought the Triforce itself; you added that little detail yourself. It was said the people desired Hyrule, and this was signified by Link running toward the Triforce; Hyrule's symbol. And then the Dark Tribe appeared in front of the Triforce, as it was said the magic dwellers appeared to rule Hyrule. Can that symbolism not be any more obvious?
And as Jumbie said, a probable explanation why the sacred place (not "Hyrule", though they are the same thing, the sacred land is, again, important only because of the Triforce) was coveted is that TP deliberately refrains from mentioning the Triforce by its true name; it would only be logical to use imagery to drive the point home.
And anyway, the Triforce is what always has caused strife in Hyrule, so why would this time be different?
Now we know the Dark Tribe did not take the Triforce because that would lead to some real problems regarding the Zelda universe, so that really leaves us with one conclusion as to what the Triforce means.
Nothing says the light spirits did not appear before the magic users touched the Triforce (in fact, it is very obvious they did), so that's not an issue either way.
