This is necessary because different players are in a different stage of progression, and there is more or less a constant influx of characters who still need someting to accomplish an objective (either new players / slower progressing players or alt characters of players, who have already done this content on any other character). But for the single character (or the player with alts), things end up in repetition fast. Flying is a great tool to combat the fatigue which arises from such repetition (like killing mobs over and over, which should be dead already because you have killed them at some point of the story before), because it allows you to skip irrelevant things. It has its function as a compromise to prevent burn-out.
And especially for people who like flying, and who steer the mounts of their character all the time (I find it rather enjoyable, because I can pretend that my character is doing some kind of maneuver or is moving with the winds or whatever, you know, roleplaying stuff), flying adds a new level of enjoyment in the game, which turns a necessary evil (travelling to a quest area) into a good experience. Having the possibility of reaching new vistas is also a bonus. There are many people out there who not only like to appreciate the world from the ground, but also in the air.
