I made 2 logical points which have been ignored by the no mob. That is Fair enough, but I'll re-state them anyway because they are restating and restating their arguments:
1) Just because something has rarely occurred (thanks for the homework RB ;D), or even never occurred, does not mean that it is not a bad regulation, or that it will not occur in the future. Far from it. By the same logic, why bother installing smoke detectors in a house that has never had a fire? Why change from old re-tread cross-ply tyres to brand new radials when you haven't had a blow out yet? Why bother revoking sodomy laws when nobody has been convicted for 50 years? You might not think the analogies are relevant, but they are used to illustrate logic.
2) The potential for a hair trigger EGM even if it not used, still has potential to be politically, administratively and financially de-stabilising just by the potential threat of it happening.
