Another issue that faces traditional monetary systems is that the feedback loop is full of delays. By the time the controlling authority has all the information about what the economy is doing and makes a decision on what the best course of action is, the economy is already doing something totally different.
In a system such as this, there isn't that large delay, its to the minute (or even second) information on economic behavior, thus the reaction to it will be more relevant and be more efficient.
It's hard to say - the way China has been trying to handle their share market melt down is to shut it down nearly every other day (and that isn't working if you hadn't noticed).
I would agree that there is little point in "delaying things" as you just end up with a "train-wreck in slow motion" (which is exactly what we are seeing in regards to the Chinese stock market).
But overall if the sentiment is overwhelmingly negative there is really nothing you can do to stop the downward trend.
