Storable food is never a waste. You never know what could happen to the food chain,, even generators run out of fuel. Fishing and hunting is fine, but not year round and meat has to be dried or kept cold. What if the monetary system collapses? Everyone should have enough food stored to get by a minimum of a month, per person. If I have extra money at the end of the month, after bills, I put it into two things, food and silver.
