Yeah, over here we have this former rich guy (he lost his fortune thinking he was better at picking stocks than he actually was.) He got lucky and made his fortune as an early investor in a cell phone company in 2000s, and after that he's basically become a serial grifter. His covid enterprise was to buy face masks in bulk, repackage them, and resell.
Well, he got hit with a huge fine: The face masks were only approved as long as they remained in their original packaging. Once he repackaged them, they were no longer considered sterile, and as such no longer approved for medical use => false advertising
The toilet paper thing was mostly a result of mass hysteria, not an actual issue of supply and demand. There were some supply issues in Australia IIRC, but most countries would absolutely not have had any toilet paper shortages if people hadn't all panic-bought far more than they needed
I don't know about that, but I do know I grabbed basically a lifetime supply of hand sanitizer a year or so ago because the grocery store was so overstocked they were giving them away for free, LOL.
No, hand made masks. Especially when it surprises the officials who should have known it was possible and beefed up supplies of the real thing. The first few months of Covid were a wild ride on knowing what would be the best choices of DIY protection, and Etsy and other sites were crazy.
I 3D printed a few dozen of these visor things for my local hospital that took 3 ring binder dividers as face shields/sneeze guards. Several ended up multi-colored because I used the ends of several spools of filament for that.
I've still got about 100 or so of them. I was mass printing them as part of a coordinated project. We basically managed to saturate the local area with them. Once demand suddenly stopped, I was left with the next batch ready to go. I've still to find a good use for them.
