These debates are usually fought by those that don't fly over water, in the clouds, over mountains, or in places where an un-powered landing means certain death.
Only an idiot pays $3 mil for a single engine aircraft, thinking that some how years later, after 5000 hours of hoping that he doesn't have to ditch his aircraft...NOW he can reap the benefits of only having to pay for one engine to overhaul.
Reminds of doctors buying a $450,000 Bonanza, when a $150,000 Cessna 340 would have been a much better choice, but hey, they thought it was a good idea to not have to spend a week, and $1000 working on a twin rating.
This argument would be mute if everyone in here had to take off from Bagdad to Kandahar, knowing that ditching at anytime meant you would get your head cut off on the internet. Amazing how all the statistics would go right out the window.
Carry on.
