This suggests that the "designated point" close to the boundary could not exist, because the "C" would already have collapsed.

However, the "C" would not have collapsed because, in the bigger picture, it is part of a complete circle; so what would cause collapse in that area when a measurement was attempted?


You're half-right. The collapse would occur throughout the circle, thus causing the whole thing to collapse. That is why we would expect a denser "outer" universe to collapse - you'd have an "infinite" number of 'C's (due to travel speed of gravity), resulting on a net inward acceleration throughout the "interface".
