Peak Prosperity has some great insights on the hoarding topic. Their view:
You _should_ hoard if you are way ahead of the curve and prepping when nobody else is prepping.
But, if everyone is in a panic and there are shortages you should be generous, understanding of the real needs of others, and respectful, and only buy what you really need (which hopefully is very little since you already prepped).
Guessing it wasn’t sugar free.
