I agree that it is confusing.

Charge, current or current density are the fundamental quantities in electricity, not potential. It should be possible to set this out without recourse to potential, which you had to do to 'explain' the contradiction.

Indeed there is another thread currently raging where your method would fail. Is it therefore fair on students to introduce it?
