The cold, hard fact is that if the bank had sufficient assets to let depositors withdraw their cash, then they wouldn't be in receivership now.
You can argue that they actually do have sufficient assets, but they just can't access them right now, and we just need to wait ten years for bonds to mature.
But that argument only makes sense if you also say that large depositors should wait ten years to get their money out.
Naturally, a dollar that you might receive ten years from now is worth a lot less than a dollar you can actually spend today, and if regulatory sleight of hand obscures that essential fact to bail out the 1% of the 1%, that would be extraordinarily unjust.
