It's dumb to hoard toilet paper because...
1) if you do the math, your family likely will never need all that supply for even a full month "lockdown". (They haven't permanently discontinued production...)

2) you really do not want other non-stockers in your shared society to go without their monthly 2 or 3 rolls, for hygienic and plumbing reasons. (People will start flushing paper napkins down their toilets, I suspect.) Please don't overstock out of fear. That goes for the food supplies too. Sometimes, even in times like these... less is more.
