Rereading, I found this the key comment of the OP.
The OP states as the most probable reason why some are enjoying the game is because time is not as much of an issue. I find that very telling. As if the availability of time determines enjoyment of a game.
I was enjoying the game (extended break atm) because engineers weren't as much of an issue for me. I tried it, upgraded FSD twice, engines once, didn't like it, looked for something else to do. This means that 2.2 didn't have that much new content to keep me occupied, hence the break.
We'll see what 2.3 brings.
You surely mean 2.1 and 2.2 instead of 2.2 and 2.3?
