Yes and no. When we write equations and draw equivalent circuits, we can
certainly pick any point we wish as a reference. BUT -- mother nature
does care about our equations, or how we talk about or try to understand
the laws of physics. We can CALL earth a reference point, and it might
be OUR reference point, but it may not be mother nature's reference
point. )
