I think the primary idea of an unincorporated town is that it isn't incorporated as a municipality with its own government? In places like Montgomery County, MD (which doesn't have incorporated individual towns) it would be very confusing if all the mail had to simply be addressed to "Montgomery County" despite the fact that almost everyone refers to its individual unincorporated areas as if they were actually separate towns.
