Personally, I think this is Beth's way of satisfying everyone who was upset with fast travel being put in the game like myself. xD
I think it'd be funny if every time you fast travel, you run the (slight) risk of three days moving on and you waking up (possibly without some of your equipment, which you can either buy back from a shopkeeper, find laying around, or ask nicely to get it back from someone/steal). You'd also wake up in odd places, alleyways, the pools of water, behind a forge, etc. Last, but not least, NPCs would heckle you for the next day or so about what a jerk you made of yourself.
It'd be like you got black out drunk or something and didn't remember how you got there.
