The 2008 collapse saw initial bailouts of $500b.
A subsequent $700b was approved and executed, and later on over $7t where commmited (but not all used) for bailouts.
That easily puts the bailouts that banks needed in order not to go under at $2-3t. That's nearly 40-60% of depositor liabilities.
If the bailouts don't happen if JP or BofA go under (for whatever reason), then I don't think the 99c to the dollar theory holds up.
How long would that take take and what about the overheads of winding up a bank? Also, what about the ranking of different kinds of creditors - depositors would only be kind of creditor if a bank was wound up?
