I'm just going to stop you right there because your entire theory is based off of multiple assumptions.
1: That Frontier designed ED to be played like it was in the 80s.
2: That the majority of people complaining about "the grind" are impatient "want it now" types.
3: That your way of playing the game is the absolute correct way of playing the game.
1: It's just not true or we'd have true Newtonian flight like the original games and not a trumped up arcade flight mechanic with artificial limits on speed and maneuverability to keep things equal. It's not a single player game, though it can be played solo, it's designed in such a way as to encourage the use of all facets of the game while not meaning to punish you for skipping out on any single one, though engineers has proven that it will do just that.
2: There are "want it now" types in here but that's not who's doing the majority of the complaining. People play games to enjoy them and some people require a sense of achievement to reach that enjoyment. Spending 5-6 hours of your week looking for parts that may or may not show up randomly in a handful of places does not lend itself to either a sense of achievement or enjoyment. Personally, as someone who spent years training skill books in EVE Online, as well being very open about my distaste for the grind in this game, I am well acquainted with the amount of patience required to wait years to have what I want, while openly building my reserves and meeting my "joy" needs in other areas of the game. So you can kindly shove that line of thought where the sun doesn't shine.
3: None of us are ever right where this kind of thought is concerned. Everyone plays their own way. To berate any one single player for not playing the game the way you do or the way you think it should be done is asinine. Some people want the biggest and, by perception, best ships in the game as fast as possible just because. Some people think they need them to be better at BGS/CG activities (Though, arguably, the Cutter is pretty much the best CG ship). Others want the ship that best fits the current DPS meta, the best ship for the exploration meta, trade, mining and so on.
Like I said in a post yesterday about rank grinding. If we only had one grind, I wouldn't mind it at all, but we have grind on top of grind on top of grind in this game. Anything you want to do outside of RP or basic mission running, comes with a grind.
