You can't just take away the answer just because you don't like it.
Being convenient IS the answer (and it's not just about logging in and out)
1 - Not having to do the MSQ
It takes like 40 hours - actual play hours, not including life hours (you know, sleep, work, school, and enjoying other forms of entertainment)
And that's just for ARR part 1 + part 2. I don't know how much it is for the full thing, but probably about 60 game hours.
Whereas a person who really wants to can level a side job 1-60 about 13 game hours.
2 - Not having to redo UI layout and hotbars
3 - Not having to convert macros to shared macros because they were done as personal macros
What, not everyone thought in advance that they'd have to
4 - Not having to lose out on your friends list, LS , etc..
5 - Not having to log in and out
Sure it's not that hard right now during offtimes.
But when a new patch is released, logging in and out = having to wait in a log in queue.
It's also nice when you're chatting with a curious new person to be able to show them things from a variety of jobs without having to make them wait for log in/out all the time.
6 - Reuse gear and use existing gil/tomes farmed on higher level to buy gear for non-reusable gear
*OP asks why other people do something
*OP negates answer given because s/he wouldn't personally do that
Plus on a main it's a lot easier to buy gear, including non tradable gear like tomestone gear, for an alt
7 - Trading between alt sucks
If a person wanted to use their main to help their alt, they have to either:
* log in, put in FC chest, log out. (what if someone takes their stuff because they took too long? What if there's no room in the FC chest and they're not supposed to take stuff out?)
* Use an in-between person to trade
8 - And most importantly, it's faster
There is the armory bonus to level faster. There are other options than just "hunts, fates and duty pugs". Combined with #6 and a chocobo who's already leveled and actually using in some of the leveling methods, it's just faster even if using the slower leveling methods like fates and leves.
POTD is the #1 way to level 1-60, but there are a multitude of leveling options:

9 - Entry sub (for those who use it) is ONE (not 2) character per server (with a max of 8 characters total across all servers).

10 - For people who use cash shop and they want to be able to use the items they bought, some items have to be bought PER CHARACTER instead of account-wide.
Old school mmos relied on people grinding for the sake of leveling (via mob farming and dungeons), not story quests, to level.
