I wrote this up in longer form in another thread, but what if the world just kept going while you were resting. Scouts might notice you nearby so the goblins would be ready for your attack. Or the druids manage to complete their spell or piss off the teiflings enough that they start fighting. Or the merchant sold that thing that you really want. Missing out on opportunities or having problems boil over might be enough incentive to discourage excessive resting without having to make hard rules against it.
