(Last year, I used a 20m dipole at 30 feet, operating out of my van.
Everything floated above ground without incident and many QSOs.)
I value your opiniion.
In Marconi opinion:

"By "connected to earth" I do not necessarily mean an ordinary metallic
connection as used for ordinary wire telegraphs.
The earth wire may have a condenser in series with it, or it may be
connected to what is really equivalent, a capacity area placed close to
the
surface
of the ground (Fig. 4).
It is now perfectly well known that a condenser, if large enough, does not
prevent the passage of high frequency oscillations, and therefore in these
cases
the earth is for all practical purposes connected to the antennae."
And Wiki:
"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 such as
ships, aircraft, and spacecraft 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:

What is your point is (other than demonstrating copy-and-paste)? If it is
that "all aerials require an earth" then you're clearly ignoring previous
postings which have said that this is not the case.
The Wiki item doesn't seem to appreciate the difference between a return
path on a circuit board and a connection to earth.
