$120 for a box of ten N95 masks.
By the time officials admitted they were "helpful" (because of course they were, there's nothing particularly special about Covid in that respect), it was already way too late to get masks. Because anybody with any basic knowledge of disease and medicine had already bought up all the supply long before.
Another way of looking at it is in a betting scenario. I want to make money. The two options I can bet on are
a) Based on decades of scientific evidence, buy fuck loads of masks on the likelihood of them being anywhere from moderately to highly effective.
b) Masks are useless based on two early studies in a highly unstable situation with little accurate information and low confidence, counter to established medical practice with no other basis in reliable evidence.
Guess what I'm betting on. Further, the risks associated with being wrong are far lower with option A than with option B.
I don't like being lied to, but in this case I think I have some forgiveness because the end goal was justified (at least in my mind). It's such a weird feeling though, I'm very conflicted about it.
Some proportion of those people are disaster preppers that bought a ton of masks, just like the toilet paper people.
