My understanding is that reactive power does not show up on OUR bills

With regard to your last sentence, electricity utilities measure reactive power used by high demand customers and charge higher rates accordingly. (Some industrial users install power factor correction schemes at their factories to cut down on these higher costs.) But we small fry are not charged for reactive power.

Inductors are said to consume reactive power . . . that makes me wonder if perhaps our use of inductors in AC power tweaking is putting a disproportionate burden on the grid . . . not that the sum total of what we do makes a great deal of difference compared with impact of indstrial users . . .
