Obviously when traffic is stop-start you don't enter the box
junction until you can leave it. But if traffic moving at full
speed across box junctions refused to enter until their exit was
clear, the capacity of the road network would be slashed, and
gridlock would result, the very thing that box junctions are
supposed to prevent.

Which is what I said

No you said you shouldn't enter the box until the driver in front has
exited because then your exit is not clear.

If the traffic is flowing but not at such a speed that the box covers
the 2-second gap you should continue across in a normal manner.

I was referring to a situation where the driver in front clears the
box then stops needlessly leaving you stranded.

Now if the rules were enforced via officers at the scene, they might
use common sense. But as long as it is enforced by automatic cameras,
it is obvious which driver would be penalised.

I think it should be illegal to change lanes in a box junction, for similar
reasons.
