This will just force you to be more careful about maintenance and fuel cleanliness, not bad habits to have).
One could argue you can be as careful about maintenance and fuel as you like. But if an engineer doesn't correctly fasten an oil hose (seen it) or you take a bird (seen it) then you're gliding. And this rubbish about always being within gliding distance of a field? Well you may take that chance if you like, I'd rather not. I can think of several areas I'd rather not be trying to glide to a field. And you get one chance at it. That's it. So you better hope you're at the top of your game when the unfortunate event happens.
I don't want to sound anti the single. I love them, think they are fantastic machines, especially for the owner pilot. If I had the means and I flew myself places on business a TBM 850 would be hard to beat. But the OP specifies family and safety. It's a no brainer.
