Some say there is no such thing as DC.
What you see as a DC voltage or current is the result of a stable dynamic system, obtained through a proper balance of impedance modules, transfer blocks and feedback phenomena, even in the simplest circuits with no apparent reactive component.
Furthermore, one can say "high impedance" or "low impedance" when the reactive component is simply unknown. Take for example an opamp: the input stage is often JFET, thus presenting very high resistance and very low capacitance. Short said: a very high impedance.
