While this was in part a good article, it didn't shed any new light for those who were already experienced with all these things he mentioned in it.

Lower resistances only lower, to minimize the effect. However, the cap still has these effects. Simple experiment. Simply take a large bipolar and connect it in series with a DC couple amp. Now we are working with 8 or 4 ohms, so very low impedance circuit. But the sound changes substantially. Point made.

As a coupling capacitor is "swamped", the low frequency response also raises, so another problem. So we must now increase the capacitor size, adding more problems with DF or ESR.

Still not an ideal situation, to be sure.
