There's always the issue of players not caring. And by that, I mean players who accept that plot will continue to happen regardless of what happens, and they don't mind it when bad things happen. It's just more plot. The dungeon reinforces with more enemies? Okay, that's more plot to devour. The evil wizard completes his ritual and things get worse? That's more plot to devour. All the treasure is gone? We move on to the next plot location and get treasure there (or not).Anyway, players learn they cannot set the pace of the game to suit themselves in all cases. Sure, there will be times they can rest safely (especially at high levels with spells like Teleport come online), but there should be plenty of times when they can't. If you always allow them to rest on their schedule, you are allowing the problem to persist. Resting should come when the narrative of the story allows. Sometimes player choice will drive that, other times it won't.
I'm not suggesting a group that takes a long rest after every single encounter, consequences be darned. But instead, players who simply don't mind moderate consequences to their choices because it's simply more plot. Nom nom nom.
