I will leave you with this parting thought. All that you are saying is
that the power at one point (special case: away from any energy
storage device) is the same as the power at another point in the same
wire (special case: an infinitesimal distance away). No rational
person would argue with you on that point. However, that is NOT a
general case and in no way proves that power is conserved in general.
It is simply a special case where there is a one-to-one correspondence
between energy and power, something I pointed out earlier.

The throw of a switch can cause power to be created or destroyed. The
throw of a switch cannot cause energy to be created or destroyed.
That's the basic conceptual difference between power and energy that
you are missing. The same thing is true for current vs charge.

In my energy articles, I took advantage of the special case of one-to-
one correspondence between average energy and average power. You
neglected to do that for your instantaneous power calculations and
proved beyond any doubt that power is not conserved. Your own
continuity equation posting indicated that you had erroneously omitted
something important from your previous calculations.
