Unless what you want to spend time on has leveling as a prerequisite. One of the goals for me is to have more end game content (more capped jobs to play). This involves leveling. I could choose to not level efficiently, but then that just pushes the end goal further away. If running content directly provided the same XP as daily roulettes I'd have more ways of reaching the same level of efficiency, which I'd prefer.

It may be efficient in exp/time, but there are other criteria by which you can value your time. For example, many people suggest deep dungeon as a fast way of leveling, especially for DPS like me. I am ok with running deep dungeon, but it's not my type of content, so I choose not to do it for leveling and only do it if I want something from it (other than exp) or if I am joining other people.
That's true, XP/time isn't the only metric of value but you do have to take it into account if you want to do anything that has a level requirement. Most of the game has such requirements. While I don't have to level, there wouldn't be any point to playing if I didn't because I wouldn't be able to do anything I enjoyed.
