This is valid but a half-point. I still have rather bitter memories of my brick-and-mortar bank slowly bleeding my checking account dry during a period of low income for 'failure to maintain a minimum balance.' Public overreach and private greed are two sides of the same coin, and addressing one without the other is a bit facile. The tyrannies you describe are often tolerated and sometimes engineered by economic incumbents who want to maintain their dominant position.
It's not that I think your view is wrong so much as incomplete.
