It points out all the people making money off people who want to prepare for some emergency. They have a good point but the miss the most important point. This is all about risk management.

Once the risks are prioritized then one can determine means to avoid or reduce the impact of the risk. You have a plan of action. If this is done correctly then one can budget time and money to implement these means. The goal is to follow the plan of actions so you do not waste resources. Without such a plan and corresponding budget it is very easy to waste both time and money and in even increase your overall risk.
