Everything you mentioned is actually in instant's favor. Logic/internal consistency with other game mechanics (outfitting, repair, refueling), lore: hyperspace drives and bulk freighters, gameplay: literally the core instant argument, BGS has been proven to be mostly static, CGs is an other reason for instant so no idea why you listed it beyond hiding it in the middle of your list for padding, player group/player interactions: not possible while waiting unless you're referring to chatting in [local] while docked.Apart from the upper-hand in: logic, lore, internal consistency, game-play, BGS, CGs, player group interactions, player-player interactions, and the fact that the only reason this is even an argument is because someone blurted out instant in a stream.
Or maybe you were being sarcastic in your sarcasm? A trojan horse argument? I say this considering you were pointing out all the things wrong with the delay timesinker arguments in one list. There's no other logical reason why you'd put CGs and gameplay in your list.
