Alternatively, you could assign maintaining the mask inventory to admin staff. I know they often don't have advanced degrees, but I can't imagine they'd do a worse job of it. Actually, they'd probably take the job a lot more seriously than the "experts" who are in charge currently.

Assigning such tasks to a central body seems like an extremely fragile design, and as evidence for this assertion, I offer the current state of reality. I find it a rather convincing argument, but then I'm probably quite biased.
