We have to fall back on that old hound logic.
Logic would suggest from the description of the engineers when they were released and current game description that they don't actually advertise their presence or have a large number of people sitting around their bases doing nothing. For instance The Dweller, an engineer described as a mysterious contact in the underworld just isn't going to operate like that.
That may very well be the case for the Engineer you choose to mention,(and I'm sure you can dedicate time and effort to find more to support what you say and dismiss my post) in reality it's a bit different.
I'm at Sirius and there are two and a half million people there, Now I want a 6A PP for my ship and I have just such a module stored 155 lys away in Levy, now, I could send for that one or go buy one from... (looking on the internet for outside tools...which is silly) BD+49 1280 which I'd rather not do because the PP I have is underpowered and I'd have to juggle systems power distribution and avoid possible interdiction in a ship that's half built.
So the reasonable thing is...
If someone is willing to bring my PP 155 lys can they instead get me a New one from 51 lys distant, there two and a half MILLION folks in Sirius and one of them is twiddling her/his thumbs... this would allow me to do the washing up.
The above is not Gameplay bought about by the destruction of my explorer ship 15,000lys out through lack of 'game' information, it a silly grind to get back to where I was!
The Ship that was destroyed is still some 40 hours away and I'm trying to do 'something' in the meantime...
Thank you for your understanding,
My request stands
PS, and now my Tea is cold!
