People hoard because of artificial scarcity. There's nothing wrong with being prepared, but dairy farmers are paid to pour out milk from over milked cows, to keep prices above a set threshold and take a writeoff, rather getting a writeoff to donate it to surrounding communities. Del Monte peach farmers were going to destroy over 400 cling peach trees in California, because Del Monte is closing, rather than find new buyers, grain is wasted, water is extracted for a pittance, bottled, sold back to communities, rather than communities investing more now to make sure clean drinking water is conserved and distributed for an affordable price for their community members, medicine is unresearched because the profit margin wouldn't be high enough, etc ad nauseam.

That's only because the last 5% of human existence there has been this system which rewards greed.
