There are possibly few players who could devote 17 out of 24 hours to transfer a ship. Also remembering the round leg. When I took my Cutter out there, my PC is so bad it was taking an hour and 20 minutes per 1000LYr. Each hyperspace was taking me on average 50 seconds!
So when working out these min / max conditions, it is important to factor in that not being able to play for long stretches and making do with poor hardware (GT640M mobile graphics) means efficiency can be severely compromised.
There's no doubt someone will pay these costs for all their ships to Jaques. And some of those will be rich enough to drop billions for the luxury. But they'll still need to get there and wait 60 hours before they can use those ships. They may not be able to get to Jaques twice (sidewinder tp on the return trip), which is x hours investment of actual game time. Certainly many won't be willing to do the trip several times.
So
someone will see value in those billions, particularly if they have nothing else to spend it on.
But make no mistake, those credits and 60h wait are gigantic investments. That trip to Jaques had better be worth it. Perhaps a one off, never again deal to relocate and never return.
Now just try to imagine how many would actually do this?
Most will agree very few. I've certainly not seen anyone say "I'm going to drop billions to move my fleet to Jaques". And quite a lot of players are saying "that's fine, that's how it should be!"
And there we have it. Group B, saying it's supposed to be ultra rare. Something hardly anyone wants to do. The exact same reason no one will use it across 300ly. Or 160ly. And, let's face it, no one will use it over less than 30ly. Very few new players will use it because they'll want to save their credits for new things. Very few veterans will use it for the same reasons.
Basically, the consensus from group B is "only very rich players or players who have nothing else to spend credits on should be using it and very rarely".
Why?
Seriously, is any new player going to load their first commander, with 1k credits and a sidewinder, and have this glazed eyed look on their faces as they dream of, one day, somehow, they'll be rich enough to be able to afford that glorious, exciting and fulfilling ship transfer... I just can't wait to spend all those credits I'm going to earn. Oh, I'm all warm and fuzzy just thinking about it! Let's get going!
No. They're going to buy a second ship one day and they'll notice the ship transfer page, check the delay and cost and go "nope, I'll do it myself" then continue playing toward their goals for something that's fun.
It's a nonsense assertion that this feature should be some kind of end game, luxurious dream toy. It's a basic tool. Very basic, in terms of what it actually does. The delay limits it enough to prevent abuse and that's enough. There's no logic nor evidence that FD want it to be a dream for players to work towards, nor that FD want us to use it rarely.
