Actually Jinx, I see combat and non combat as the same game.
If you have a dog and you want to teach him how to sit, but he wants to chase his tail, it is not his failure if you do not teach him how to sit. (no offense, not comparing anyone to dogs)
If you encounter a hostile Xeno that wants to beat the crap out of Zoners and if the Xenos are currently hostile to Zoners no matter what you guys do, I guess you can call your attempt to play the game without a gun - a failure.
Perhaps trying some other language or form of communications with them might succeed much better.
Violence is part of the politics too.
As for Junkers:
Junkers got their wings clipped off by the new rules not allowing them to pirate corporations in the house space. I still stand by my opinion that this is a horrible decision and rule ruined a lot of potentially quality roleplay. Everyone suddenly started to take junkers to pirate around, and to pirate ore. people freaked and complained OORP-ly instead of taking more action INRP. So junkers got screwed.
Perhaps if someone with more direct approach lead some official junker group then, that could simply FR5 every junker that did something stupid we would get somewhere.
Perhaps leaders of LN could have shut down the junker base behind manhattan. It's very simply to deny docking for everyone.
But I'm afraid that people would only complain more then and whine and whine until they would either leave or destroy all junker bases like that.
