No, the average bitcoin customer already didn't have a lot of money in "evil fiat currency" to begin with before bitcoin, and the total market capitalization of the entire bitcoin system is smaller than about two hours of trading profits at Goldman Sachs.  Why would they care?  Moreso, with people like me who think most bitcoin embracers are completely nuts to choose this system over putting their assets in a bank, why would they bother?  There are already enough voices of dissent out there.
