> I am not sure that using heights is the best way to get independence
Another excellent trick I learned from Cremona for getting independence is
to use *homomorphic images*. I.e., reduce to a direct sum of groups of
points over a finite field (all tensored with F_p, with p coprime to
torsion). Then the rank of the group you have is a bounded below by the
dimension of the image.
