It's a simple idea that could easily be implemented with the existing mechanics, as they appear to work. Since most of the people who play in solo do so to avoid pirates and gankers, the only way to lure people out of solo is to drastically reduce the risk of encountering those types. And I think you could do that by instituting a "death penalty" for anyone who attacks an unarmed ship. Basically, attack an unarmed ship and your commander is erased as if you had hit the menu option yourself. All your ships, all your money, all your ranks-- gone. Enjoy your new Sidewinder!
