Yeah, and a meteorite might slam through your roof and kill you while you’re sitting on your couch. A giant sink whole might open up under your bed while you are asleep and swallow you up whole (actually happened in FL). You have a better chance of getting killed driving too and from the dive site. I think what people are saying is that if your gear is maintained to proper standards from the inside of the tank all the way through to the point where your lips are wrapped around the mouthpiece and everything in between, and your situational awareness and skills are what they should be to dive safely then many or most of us are willing to accept that using scuba gear has a very low level of risk where a pony bottle does not add enough of a safety factor to bother with it.... and even well made items can have defects/quality issues that can result in failure (sometimes sudden with no obvious, advance warning signs).
... but "none" is not zero!
... and "nearly" is not all!
When you can gurantee no one will ever have an issue that could have 100% been avoided in advance, you might have a point. Even then, we're human - so not perfect and things that might seem obvious can be missed by even the most diligent person on any given day!
It's great that you are somehow perfect and will never be in a situation where a pony bottle might save your life. The decision to carry one is a personal choice - but I can't see how anyone can characterize it as ever being a bad idea!
Nothing in life is a 100% guarantee, nothing.
