Actually I think that's kinda moot statement, there will be
chaos in any country if it's entire parliment was killed off in
some disaster, be it a good government or not. The point is so
obvious it's rather silly to be using it as an example of "you
can't do without us".
However if that parliment was taken over by the legal and proper
channels I think it might be a very different story, and of course
for some they might realize rather uncomfortably that Singaporeans
indeed, 'can do without you'.
