You'll have to excuse me, babelfisch. My sarcastic comment wasn't directed
at you, but rather to the anti-Open "PvE" community as a whole.
There are plenty of parts of your post that I disagree with. I'll discuss them...
The first is the use of the term "Traders" as if to suggest that everyone who trades in game does not engage in PvP. This is incorrect. There are a lot of people who trade in open, and when you play in Open you are engaging in PvP to some degree, even if your play-session winds up being devoid of other players.
PvP doesn't necessarily mean fighting to the death with another CMDR. When a player is interdicted, they have engaged in PvP, regardless of whether or not that player stays to fight, or runs to live and fight another day. Even evading or escaping an interdiction in supercruise is PvP.
The idea that in order to outfit their trading vessel with defensive combat modules, that a CMDR must then give up trading is an absolute fallacy. Using the "Rinzler model" for a T-7, your build would look like this...

That's a T-7 with a solid 272 tons of cargo space. That's
huge. If you wanted to really juice it up, you could swap out that 5A shield for a 6A and get some extra mj out of it, and you would still have 240T.
You made the statement "He could also use the engineers". You're absolutely right, traders
can use the engineers. Even with some fairly decent rolls on the 5A shield and one booster, Rinzler's T-7, with 4 pips to SYS is sporting somewhere around 1000 mj of shields, and that's not counting the additional resistances that come with those rolls. That's accounting for G5 shield and G3 booster access, both of which can be gained from Lei Cheung - an engineering path that a player can unlock in a couple of dedicated sessions.
And that's more than enough shield strength to high-wake out of a simple gank if the trader keeps their wits about them.
In the end, you ask "why"? A PvPer wants to be competitive, but a Trader doesn't need to, and you simply end the discussion by saying that it's best to just take your ball and go home - and
that's the issue I have with a lot of the discussion I hear from the "dedicated PvE'rs", and why I wrote the post I did. (Again, this isn't necessarily directed at you) It's not that they
don't have access to the modules and mods that would allow them to compete against combat ships in Open, it's just that engaging in such pursuits is totally beneath them. How dare anyone suggest that they bother themselves with the PvP jock game? Don't you know they're members of mensa? They are much so smarter than all of that...
