Oh absolutely, but I am not sure that the wealthier people don't have access to cash. That's what I was addressing. They may use plastic on a daily basis, but I'd be surprised if they didn't have near immediate access to liquid assets, including some that are easily bartered with. I know at least two people who have gold in various weights, for example. I am not one of those two people. Some have art and jewelry, those could be bartered with - if things got really bad.
