It may be true that one never actually flies the MSA. However, I don't
agree that MSA has no relavance for routine flying. If that is the
case, then OROCA also has no relavance either, as well as all the
obstacles depicted on the IFR charts. If you are descending below MSA,
then you better be on a published segment of the approach. It certainly
has value in that respect.
