The only thing impeding their progress is their resistance to learning anything. This is an absolutely toxic mindset to get into a new game with.
I have never said "Don't ever use the docking computer." I don't have a problem with him using the docking computer, however it's important that he needs to know how to dock. This isn't about "the correct way" or whatever, when it factually is correct that you have to dock one way or another. If your docking computer gets shot, like you said, he has to know how to do it. If his canopy is breached and he has seconds of oxygen left, he certainly doesn't want to wait for his docking computer to get him in and waste time. If it's "not a big deal" to him, I hope whenever he gets an Anaconda eventually, he's so overflowing with cash that the ~15-20 mil insurance hit every time he dies because of something like that, or the docking computer fucking up and crashing straight into the station, is pocket change to him, but I seriously doubt that.
He wants to play the game in silly and impractical way thinking he doesn't need to learn a skill that's Elite 101. This isn't "Oh you're not playing my way", it is effectively like breathing! "Oh, I don't need to breathe like you do. Stop criticizing me for not breathing your way!"
This isn't a difficult concept, just people like him are turning it into one.
