>the shear forces generated from an INSTANT acceleration
I see what the issue is here. B simply says that the relative velocity is conserved in part specifically to counteract what you are talking about. Chell comes out at the velocity of the moon, not starting from the velocity of the earth and then accelerated to the velocity of the moon. There is not actually a force involved in B. The upper body moved at 2000 m/h along with a portal moving 2000 m/h while the lower body doesn't move with a portal that isn't moving. There is no deformation of the body, which means there is no damage.
