I mean, I find the desire to have a day/night cycle to be pretty arbitrary too. .
No, I meant it literally.
You said that days in games with a day /night cycle are too short, but that's simply not true if you make them longer, isn't it?
That said, not sure what' strikes you as so "arbitrary" about having a preference for consistency and verisimilitude over highly abstracted and convoluted subsystems like "We'll swap between day and night whenever we'll feel like".
