Honestly, and this speaks more to the idea of economy, money is just paper. People, humans, assign value to it. The "dollar" has no real value...at all...it is just paper. I agree with you, too many "end of the world" movies in someone's head...
Being all cash in a collapse type situation is not going to mean squat other than you have some fire starting materials, but I digress.
The point in my post is just a reminder that this is a professional forum for professional investors, not this nonsense about the world ending and how we need to stock up on emergency supplies.
In fact, I would argue that taking such a stance hurts the market. Especially if enough crazies buy into the theory (see 2008 crash).
My comments and posts are simply my opinion. ALWAYS DO YOUR OWN DD.
