I am indifferent to Tidus mainly because of the confusing plot elements. Does he not care that he is a part of an Aeon and not a real person, or am I recalling correctly that he does not actually address this during the game until he disappears at the end of the game?

If I recall correctly, the Fayth for Dream Zanarkand is located atop Mount Gagazet and the Aeon for Dream Zanakarand is located somewhere in the vast ocean in an unspecified location. That would explain why you cannot visit it in the Airship.
