You've pretty well answered your question, why ask it?
Let me try and reframe my original comment for you. I do currently think that Boeing should be regulated more, but I'm not convinced enough of my own reasons. So I'm wondering whether my perspective would change if I heard compelling alternate ones?
I can't really help you as I agree too strongly - see my other comment elsewhere re. stress testing.
I can't see any possible reason. The only people reliably who might answer that things are ok as-is are boeing themselves.
