I hear what you're saying, but "because we have so many of these planes out there" isn't a rationale that gives me a lot of confidence for justifying a waiver. In the grand scheme of things I'd rather see them stop building shitty planes.
Don't fret, the American government is doing all it can to ensure Boeing's investors' MONEY is worth more than a few hundred people who are already dead. Boeing pinky promises it will never, ever happen again. And if it does, it's pilot error.
