True that !
Prepping is all about put up essential and life saving goods for survival, overcoming "normalcy bias", and during surplus, being not dependent on others. or government largess.
Hoarding is buying more than your needs, not a survival issue, and counting on its value to increase (ie: alcohol, soap, sanitizer, etc., etc.) which causes a shortage for others.
By their definition, all our ancestors who got ready for a winter of privation and no crops were hoarders for storing up the year’s bounty to get them to survive until the next year.
