If you pick the text you posted here yes, he was an idiot by your
definition. He wasn't really an idiot, unlike you.

Because the earth is NOT "in these cases the earth is for all practical
purposes connected to the antennae" for well over 99% of all the antennas
in use today. Because it doesn't need to be.

You simply do not know that:
"In electronic circuit theory, a "ground" is usually idealized as an
infinite source or sink for charge, which can absorb an unlimited amount of
current without changing its potential." and,

But the "ground" you are referring to in this paragraph is NOT the one
you are in the next. One is an essentially infinite sink, and the other
ignores that property entirely.

So you are arguing with yourself here.


"The use of the term ground (or earth) is so common in electrical and
electronics applications that circuits in portable electronic devices such
as cell phones and media players as well as circuits in vehicles may be
spoken of as having a "ground" connection without any actual connection to
the Earth. This is usually a large conductor attached to one side of the
power supply (such as the "ground plane" on a printed circuit board) which
serves as the common return path for current from many different components
in the circuit." From:

The same was wrote by Marconi.
