OK.  Then it's not as crazy as I thought.
Just poorly expressed.
After all, a battery can be thought of as a
reeeeally high-capacitance capacitor.
This must be a severely overdamped RLC circuit.

What Preyer calls "steady state" should be reworded
as an _intermediate_ timescale (tau).  Some things have
happened on a time scale much shorter than tau, such as
relaxation of the current pattern, radiation, inductive
effects, et cetera.  But RC relaxation (i.e. discharge of
the battery) happens on a timescale much longer than tau.

And then I'm not sure that this scenario should be
called "the simplest circuit".  This is several steps
removed from utmost simplicity, IMHO.
