Seriously, the run on toilet paper was a strong counter-argument.
If you suspect there is going to be a run on toilet paper, the obvious choice is to stockpile toilet paper before it is all gone. If you buy just enough for the next couple weeks, and you risk running out because of shortages.
The optimal solution to this IMO is to embrace raising prices during crisis, because then the market ensures that those with the most need get access to goods, and it eliminates the whole point of hoarding 3 months worth of TP naturally.
