Why, wouldn't a lack of landing clearance result in an automatic go around and an automatic following of the published missed approach?
No. The controller isn't going to let you happily continue down to some arbitrary altitude before deciding to GA.
Let's take your scenario, where you're on final without a landing clearance, you're not just going to sit there in silence, are you? You'll call and ask if you're cleared to land, at which time, the controller will tell you to GA.
