or preventing a runaway panic that could creep to other banks. bank runs arent good for any bank. its the nature of how they work. borrow money short, lend it long.
granted, SBV was particularly susceptible to a run because a huge amount of their $ came from a (relatively) small amount of account holders, so it didnt take much for an essentially coordinated bank run to topple it. other big banks have a vast vast majority of account holders having small amounts of money in their account, and its pretty tough for a comparable bank run to happen there
its not like SBV is being bailed out. that bank is still being torn apart. their shareholders are out. employees are out. 2008 bailed out banks in a manner where the morons in charge of those banks kept their jobs, positions, bonuses, etc. bailing out depositors =/= bailing out the bank
