That post that you linked pretty much boils down to "because I say so", though. The argument of game impact you make there could just as easily be applied to all of those other tasks. Imagine the impact it would have on gameplay if a heavily-damaged PvPer had to wait a couple hours for their ship to be repaired before they could get back to PvPing, rather than just docking, mashing "REPAIR ALL" and "RELOAD ALL", and being back out of the station within thirty seconds? Or if they had to wait thirty minutes to refit their ship from a travel loadout to a PvP loadout?
Well it's a balance between game/narrative. There is no ideal, anyway more than you can say Lord of the Rings is best as a cinema or extended DVD version. You can make arguments either way, but the arguments are justified on balance, be it keeping viewers entertained vs immersion or gamers involved, vs immersion.
As for your explanation, you have to ask, whether the immersion vs gameplay have any critical exploits or downsides. If you have people waiting for 30 minutes to get their ship back/repaired, you lose the flow of the game as you would if you made people wait 30 minutes for people to board a ship in a film. You would have people leave the game. If ship transporation was singular - if you had just ONE ship you were waiting for and nothing to fly while you wait, then yes, insta-ship would serve the gameplay over the immersion in greater folds.
With insta-ship, the gameplay is over-served at the detriment to the game's ideology and immersion. Ship just... appears. It makes no sense in-game, out out of game, it is a non-essential trucation of immersion. The player can still do things without his ship.
The same arguments that have been made against ship transfer (that it would violate realism and decrease the amount of downtime for PvPers) could just as easily be made against instant repair, instant reload, instant outfitting, and let's not even forget instant respawn. In fact, ESPECIALLY instant respawn. People already use self-destruct as an instant teleportation system, sending themselves instantly back to LHS 3447 in exchange for the cost of the ship they were flying. Everyone arguing about teleportation is a little late, because it's been in for a while. Anyone who flew an Asp out to Jaques could instantly teleport themselves back to the bubble for just a mere 7 million credits.
That's because as I said, all is balanced out gameplay vs immertion. PVP requires a certain amount of pacing to keep playing.
Your arguments seem nuances on a basic point "I want insta-teleporation". You aren't meant to blow yourself up to get teleported back for a 7 mill ticket. It's an exploit used but not part of the gameplay-immersion balance. If there was a button that said "back to the bubble for 7 million" that would be considered immersion breaking. There is a difference between players working around Elite ideology and Elite actioning ideology that doesn't fit or benefit the game, just player entitlement. It's all about balance. There is no need for insta-teleport. It's not balanced.
