In all of your examples the key factor your argument depends on is player interaction, not being in Open. Progress is generally slower in Open, but you can receive help as well as face an adversary. IME it more than compensates, and it is more fun.
Your central point is that Open is inherently dangerous which is true enough, but completely overlooks how much help can also be found there, and how much more exciting & fun that can be. You are repeatedly telling only half the story. I have played in Open for years, travelled all over the place, helped, received help, been attacked and generally had a blast. It is a different way to play.
Your arguing the danger from the stance of one who apparently makes it a dangerous place (by initiating attacks, something I don't usually do) is becoming tiresome. You choose to play in a more exciting and risky way, your reward is your own personal satisfaction (except apparently not because you are clearly frustrated). All of the risks you describe can be mitigated, the only issue is whether a player complains if their risk doesn't pay off.
The black & whitelists aren't going to go away. Nor are the players playing in a way you don't approve of. They probably don't approve of your style either. Accept this difference of opinion and just enjoy the game for what it is with your friends, because one day we will no longer be able to play at all
