MORE reasons to long rest? But that makes absolutely no sense to the story. Any part of it. Name one thing in the story that says resting a lot makes any kind of sense.
I'm honestly not sure what you're asking. Why does sleep not make sense?
Anyway:
Because people who get tired have to rest and resting increases the dramatic tension involved when there's a looming tadpole to consider.
It also allows for downtime so the characters can get to know one another.
Again: the problem is that players are naturally inclined to *AVOID* long resting. The story already incentivizes them to avoid long resting, by the nature of what's happening in the story.

Knowing that long resting isn't going to hurt you is meta information that the character doesn't have, at least not for a while.
