 Perhaps we need to first define "high voltage," and the accepted
definition is voltage that exceeds 1 kV.  Thus, all household (110/220)
and industrial (480) sources are excluded.

Depends on the industry and which set of standards.  OSHA has one standard at 600V, but for others, even 240VAC household can be considered hazardous and requiring PPE/etc.  Yes, this does cause confusion with "homeowner" centric practices.

The major problem with HV is that a direct contact with the voltage
source is not necessary for a lethal current to pass through the
body.

Safety policies start at values much lower than "lethal".  Overall, it sounds like you've never personally have gotten zapped with even mere 120VAC to understand this.

Any HV source will establish an electric field throughout the
local environment.  A living human can be standing 5 meters
from an HV source but if he is sufficiently grounded the current
will "jump" to him in the manner of a lightning bolt.

Depends on a lot of factors on propagation. General rule of thumb for dry stationary air conditions is 10kV/inch, so a 5m arc should require 2000kV.  But there's a lot of ways to make that lower.

As I indicated, HV is nasty stuff.  Some amateurs will experiment
with HV.  I would never do so.

Well, I could invite you to stop by the lab at work, to see if you can withstand 3 seconds of ~3kV/m RF RMS: guaranteed to not turn you to ash.
