All I was saying is that the broken peg is a much bigger issue, and this one change alone isn't going to fix it.
The real protection against the "black swan" event is the 10% 'haircut' which is unaffected by this change.
Rather than argue for the change though, I will argue against the converse. In a case like we have today, why is it good to be giving authors a portion of their rewards as STEEM? Wouldn't it be better if they were receiving SBD instead?
