Just a nit - there is a frequency at which the voltages will begin not
summing to zero. That's when it is time to discard the lumped-circuit
model and go to the distributed network model or Maxwell's equations.

agreed in general. the initial premise was a couple resistors and
batteries... this is strictly true only for instantaneous voltages
across lumped components.
