Be careful what you're wishing for.

It's still easy to be a 'carebear' in Open (trust me, I did this about 1/3 of my 6 years of playing, and still do with my new Alt on steam). The ones that would cry the loudest would be the PvP lovers in the first place. That would be really fun to see them suddenly flying like on eggs while cautiously worrying about losing their precious engineered modules. Or did you perhaps miss this part of the OP: "-Remove insurance, when a ship pops, it’s gone, including engineering and ship modules." ?
I'm all for it, bring it!

Seriously now. If anything, it would support players like me.
But trust me, even a normal forced ironman mode has no chance with this community. I still remember such discussions from the past. No way. And then there's the idea of Open only in general, that has a whole bunch of (mainly technical) arguments against it. It's not just the carebears who block such a development...
