I know that was plot convinience, but on the other side, what if Merlin was not Arthur's servant, what other position he could be in? Position that let him go with Arthur everywhere everytime? If King has right hand advisor, what would a prince has?

For me, maybe position as servant was good enough if Merlin's tasks were limited only to serve Arthur's needs like bringing his belongings when travelling, preparing his food,clothes, and bath. For washing, polishing, cleaning stables, and other tasks not done at Arthur's side, were somebody else's job.
