I've yet to see any evidence or plausible explanation for how pooling funds to have one person buy a large quantity of necessities could be a widespread strategy in this situation. It seems like this is just a red herring, and that the vast majority of people tying to buy large quantities of eg. TP, hand sanitizer or masks are either irrationally hoarding excess supplies for personal use, or planning on scalping.

But even if shopping on behalf of the entire neighborhood is common, is protecting that strategy more important than deterring hoarders and preserving the ability of underprivileged people to buy what they need for themselves?
