Just to be the devil's advocate... You are on final with a "late landing clearance" due, no doubt to heavy traffic flow and lose comms. The problem with your landing clearance must be either the plane "line up and wait" or the one plane ahead who is either slow clearing or you are close behind. You watch the plane ahead lift or watch the guy ahead vacate the runway. There is little guidance as to how you would re-enter the busy traffic flow without comms. I'd think landing might be better than going around especially if doing so will result in a conflict in the case of the plane ahead taking off.
As the previous poster said, the real world is not so easy.

This is a hardy perennial topic, too.
