The investors sure don't. But I'm not sure how failing to provide a backstop for deposits would help anything here other than the big four. FDIC insurance does

The investors sure don't. But I'm not sure how failing to provide a backstop for deposits would help anything here other than the big four. FDIC insurance doesn't make sense to me for businesses. If a startup receives $25M of investment, are they supposed to split it up over 100 banks?
