1: Mythically, narratively, equipment is inherent to a character's ability. Arthur without Excalibur is just a squire. It's also a way that "normal" fantasy heroes equalize themselves with the creatures around them. Without some augmentation, they aren't "normal" anymore.
It might interest you to know that, in earlier forms of the story, Excalibur and the sword in the stone are not the same weapon. It was later attempts to tighten the stories that equated the two.
So, mythically, narratively, Arthur without Excalibur is still the rightful King.
Even drawing the sword from the stone isn't what makes Arthur the rightful King. You put the cart before the horse. Mythically, narratively, being the rightful King is what makes Arthur able to draw the sword.
Finally, within the context of the myth, the sheath is probably more important/wondrous than the sword.
Also, for the "supernatural heroes who cannot lose" crowd, Arthur's trajectory epitomizes the hero who ultimately loses everything: His queen, his best friend, his sister/mate, his kingdom, his son, and the hopes of his people.
