Can we please agree though, because this is basic, that you cannot "improve" something, by making it not exist anymore?
Seriously ? No I do not agree.
As a doctor would you rather have a sick patient with a disease that you are able to control rather than a healthy patient ? I guess maybe it makes sense because you can get more money from the patient, is that maybe what you meant ?
OK, I have a sick patient, I should kill him so he is no longer sick? Or should I treat his disease? That is the analogy here. We said "The calculation of the FRR is not optimal, how can we improve it". People have suggested getting rid of it. That is not improving the FRR, that is "killing the patient".
Killing the patient is analogous to closing the swap market and no one has suggested that. Removing the FRR is not killing the patient, it is removing the disease.
The patient hosts the disease. Removing the disease does not is any way remove the host.
