Mask is a symbol of anonymity. He doesn't want to be anyone. Tobi is just a code-name as well. He does not care for his own identity. His mission is all he cares about, kinda like the ANBU.I don`t even know why he uses a mask, honestly, would anyone recognize him if he took the mask out? and if he took the mask out if he looked like obito, izuna, kagami, shisui or any... how would anyone know who is he forreal? if he takes mask out there is no point unless he admits to whom he really is.
