But that's a hyper specific view point that I doubt many hold, but I feel like that's the view the author has.
Losses cause crunches elsewhere, via the taxing/printing/managed-decay policies which buy the banks an unlimited number of get-out-of-bad-decisions-free options.
Who finally pays is left as an exercise for the reader, both figuratively & literally.
So even if "the bank fails", there's been destructive speculative misallocation whose social costs can be far larger the nominal owners' losses.
Of course, the government also doesn't let the "systemically important banks" fail - so related politically-mobbed up interests don't even get "wiped out".
The disgusting part is where taxpayers make the banks whole for their commercial real estate losses! It is a multi-billion taxpayer bailout of private corporations.
