End the Fed people seem to think a catchy bumper sticker is an argument. Why was the Fed established in the first place? Because people were sick of bank runs and periodic financial panics.

Do incumbents in such a system leverage their status, leading to new kinds of abuses? Arguably yes. That said, SVB was a member bank of the Federal Reserve and it didn't help their shareholders when the market decided that they were over-exposed.

Looking at your assertion from the opposite direction, if you don't trust the Federal Reserve, why would you trust a smaller bank to do a better job? Sure, it's in their long-term interest to self-regulate and operate prudently, but history is full of people acting irrationally because of greed, myopia, confirmation bias etc. The fed at least exhibits moderate transparency of structure and operation - risk is distributed across a set of reserve banks, and the membership and balance sheets of the regional reserve banks are open to scrutiny.
