So what are you proposing? All brokerages must put up the collateral no matter what? Surely it is up to the individual businesses whether they can afford to, want to take the risk, etc.
Some people seem to be suggesting that when RH got the collateral call for funds they didn't have on hand, they should have instantly gone into receivership and wound the whole operation down, closing all accounts. Or something like that. They probably don't mean that, but it's the logical conclusion of what they're saying. Always have the required collateral or face instant annihilation.
