Nobody knows what the future will bring for us, maybe we will never need to use the resources we have collected for the event in which we would need them, but im glad i do have them there. Self reliance and self sustainability are very empowering things when you begin to learn how to master them. If correct preparation was in place for disasters of the past then they wouldnt be disasters, as they would have been overcome with prior planning, which in a round about sense cements the fact that you just never know whats coming, which, ultimately, answers the original question of why we prep.
It isnt the money in your pocket that will aid your survival, it is the resources that the money can buy, so buy them!
am i drifting off topic here? im just throwing out thoughts
