I think you're right. I still feel like the fact that they don't seem to be giving the mask some sort of supernatural durability is really cool. I'm assuming the materials necessary to make a really tough mask aren't just lying around. That means that yes, in a ounch Arachne could just pick up a new mask but then she runs the risk of it being destroyed even more easily until she makes a new, appropriately durable one.
