Not Liking the Mandatory Main Quest

[Tupsi]

You realize that every single quest, ever, is just:
Talk to X
Fetch X
Kill X

Right?

Indeed - Except there's generally a good reason to:

Talk to X
Fetch X
Kill X

Rather than what we typically get these days of:

Talk to X - Get my laundry.
Fetch My laundry
Kill 5 dodos.

In the middle of a storyline about the world. How does me fetching your laundry tell me about the world (and eorzea) post Bahamut? I'll be completely unsurprised if Turn 6 is fetching Vrtra's laundry.
