Actually you need to provide citation for the idea that messing with the banking system would cause a total economic collapse. Also, a bank run is probably the earliest, and most completely solved problem of financial problems. In the US with FDIC insurance, and the fact that the Fed has stepped in to bail banks out time and again, there is absolutely no reason to believe there would be a bank run. Also, banks saw trillions of dollars of revenue disappear in the 2008 financial crisis. The disappearance of revenue wasn’t the issue. The suddenness with which it happened and the unexpected impact of non banking financial institutions was what caused damage. Suddenness wouldn’t be an issue because it would have been something mandated by the government. And the non banking institutions are smaller, better understood and would have been far less of a problem this time.
