The warpage of space is gravity. No warpage, no gravity, but still space. There is a difference.

But, there could be places where the differing amounts of energy, from different points, would cancel out the warpage of space, at a particular point. Space would not be warped. Then you would have space with no gravity.

Mathematically, energy is conserved because of a symmetry in time. There is no corresponding symmetry for space, and thus no conservation of space.

Nope, all you have to do is solve the equations for a point in spacetime. Find out how all the energy affects space at that point. The curvature at other points have nothing to do with the curvature at that particular point, if the energy has already been taken into account.

See above.
