far-fetched, you can't just find Cortosis everywhere you go, it's a extremely rare material that was used to cover some anti-lightsaber melee weapons that made Lightsaber blades short out upon contact.
But even though a melee weapon was made out of Cortosis, if it was repeatedly striked with a Lightsaber, it was able to be cut.
Cortosis was indeed used to cover Shadowtrooper armor and Cortosis Battle Droids, but covering entire walls is just absurd.
