SASless, your very well written argument is accepted. And I agree that typically no new aircraft is without it's problems and the certification process, together with all the other controls, needs to be robust enough to ensure that all potential problems are resolved before the aircraft gains certification. If any issues subsequently come to life after entering service then the certification of that aircraft must surely be reviewed and suspended if necessary.
Then as an operator don't buy it until it's been flying for a few thousand hours (look up the bathtub reliability curve!)
