Thing is: if the long term necessity for increased production of N95 masks were a no-brainer, companies would commit to building facilities. If governments subsidized producers, and it turns out we end up with more masks then we need, people would accuse them of wasting taxpayer money. Making that call is hard, as companies are ramping up production and articles such as the one being discussed could mean much fewer masks are needed.

Also, it seems at least Germany is working on this. https://www.reuters.com/article/us-health-coronavirus-europe...:

“Germany has said it will foot 30% of the investment bill for companies that manage to get production of the coveted filter fabric started before year-end”

There's no way to end up with more masks than you need. Masks don't expire. If you're worried about the elastic expiring, require designs where the straps are easily replaceable or removable.

And masks are absolutely necessary for the future. Companies can't rely on society recognizing this, which is why they can't blindly commit to building the capacity for it. But that has nothing to do with how necessary masks are for the current situation and for the future. It's just another typical case of market failure, in the sense that a free market won't optimize for the same things you would if your priorities include things like environmental protection and health. This is something that needs to be regulated and subsidized by governments, who are supposed to be protecting us from future risks instead of pretending that there's nothing they ever could've done and nobody could've foreseen a global pandemic.

Also, if a government cares more about looking good than doing the right thing, then it's a bad government.

Who’s going to track which patient was treated by staff wearing donated masks, and which were not?

And if medical staff were working with multiple patients while wearing the same mask, would they have to split the discount for a $1 mask up between patients?

The fact is the hospitals gave us no path toward transferring that to patients and not their bottom line. We ended up selling most of our masks to hospitals for that reason, seeing it as the more moral option.

If so, which method are you using?

If not, why not?
