I'm not from America. I'm from Europe. So you're basically saying we need tens of billion of masks worldwide... that simply won't happen.
I understand that would be the optimal solution in your opinion. But some countries are showing good results with a not so optimal solution, which is surgical masks and home made masks.
As odd as this my sound, but at the moment you might have a larger bottle neck in N95 production than you have on ventilators (taking into account the disposable nature of N95 masks and the sheer volume required for usage, I'm not trying to compare ventilators to N95 in terms of complexity or their production lines).
Of all of this, I think an effective treatment seems to be the fastest solution (though there's none available yet), where you'd deploy treatment only to those in intensive care and ICU.
