Consider our old friend the single, isolated conductor and its

Q = C V, where C = C11, the only Cij of this one-conductor system.
Let's make it a sphere of radius a. Then if V is referred to infinity
C=4*PI*epsilon*a.
OTOH if V is referred to a space-point located a distance 2a from the
sphere's center, then C=8*PI*epsilon*a.
Nice try, but alas that violates the defining relationship
Cij := delta Qi / delta Vj (all Vk const except Vj)
because the voltage of the "object" at infinity is changing when the V of
the sphere changes.
