Because their focus is different.

A linkshell group goes into a dungeon. Their paladin has to go on a date. Someone else with it leveled can take his place. They could find someone else to take his place but you don't know if that paladin is any good or if he will mesh well with your group.

you are a master in alchemy. you've just made nq batraal glue and are about to sell it on the wards. because you are one of the few master alchemists there isn't very many batrall glue up on the wards and you can still make a decent amount of gil.

I see where you are coming from but let me make a similar example.

A linkshell group needs a very rare item crafted. Their master alchemist has to go on a date. Someone else with it leveled can take his place. They could find someone else to take his place but they will charge more than the linkshell group can afford.
