A coil could conceivably cause damage, but not the type you are
alluding to. A fire hazard possibly, accidental trips of smake
detectors, possibly, strange knocks in the walls... highly
improbable. As you mentioned, this sounds more like a polter-

Beats me. When I have asked, I am not given a response. I do know
for a fact that very simple experiments designed to test the
efficiency and effectiveness of RF ground systems show beyond a
doubt that they are a required on high powered coils, and very
desirable on smaller systems.
... If all else fails... Throw another megavolt across it!
