Selective emphasis. The key word is "possibly" - you can have an AD which allows the aircraft to fly while being closely monitored if the chance of hull-loss is relatively remote. Compare that to the Applegate DC-10 memorandum, which stated clearly that "in most cases [this would be likely to] result in the loss of the aircraft". That is the point at which grounding until the AD is applied becomes imperative.
All transportation, from walking across the street to going into orbit, involves a degree of risk management, and everyone who takes an interest is - or at least should be - well aware of that.
