I made my living as a professional gambler at one time. I'm used to carrying cash. I'm also used to the downsides of it, and the precautions that have to be taken. I keep a fair bit in the gun safe but it's not the most valuable thing in there.
In the zero rate environment we've had there's not been much incentive to bank your cash. That may or may not change.
Cash is useful in some situations where you couldn't get it, but only to a point. If things get very bad, the value of cash goes almost to zero.
