That's the point exactly. Somebody(s) dies and safety comes back around. Time passes and then somebody else (who missed the funeral) buys a boat, thinks it rides like a limousine and doesn't realize how fast things can go wrong if a prop comes off, or a drive seizes, or he thinks it handles so well he can turn it just a little tighter....in calm water...at 100 much less 130. Bottom line, before you have time to react or even blink, bodies are flying around ballistically, your windshield is slicing your arm off, and your wife is doing a face plant into your cute little billet speaker cover. Believe me having life jackets on provides flotation and rib/upper body protection (especially with the ballistic inserts). Having gone right through the cockpit wall of a race boat and been upside down more times than I care to remember, I know first hand that good lifejackets are worth their weight in platinum times 10.
By the way the logic behind rough versus calm water life jacket wearing completely escapes me. High speed accidents occur more often in calm water. Rough water slows you down...but can sink more boats.
One more thing, no matter how good you think you are as a driver...if you have kids, or people who love you.....see the picture below.
