This is the first time I have encountered the idea that harnessing zero point energy is a bad idea due to it 'creating a black hole in the energy field'.

I always thought of zero point energy ('free energy') as something more akin to solar energy; simply harnessing something that is already there.

Perhaps the solution to the horrific pollution caused by fossil fuel energy would be to harness other frequencies of electromagnetic energy besides just visible light (solar power). After all, the earth is being bombarded with a wide variety of invisible electromagnetic radiation both day and night. The earth is already absorbing vast quantities of this radiation and taking it out of the system, might as well capture a fraction of it before it reaches entropy.
