There is a difference between stockpiling and panic hoarding. Stockpiling can involve, canning, preserving, dehydrating, bulk purchasing in times of plenty, and setting up gas generators and petro. Panic hoarding is going between one grocer and the next and buying the entire stock of an item, sometimes with the intent of price gouging your neighbors, or just out of a general sense of fear. One is orderly and planned, the other is a dickish move.
