Stocking up isn't irresponsible, that's just being smart. Stocking up after you've already stocked up is irresponsible to society. Had to stop my dad from going to Sam's club every week during lockdown because he would buy another pack of paper towels or toilet paper after we found out he had 4 packs of each already. My old bedroom is his stock room now. He has about 2 or 3 years worth of toothpaste, at least a year's stock of paper towels and toilet paper and garbage bags, enough cereal and oatmeal to probably feed a family of 4 breakfast for a few months etc...
