Indeed. But if the longer radials put your wire in your neighbor's back
yard, or run out into the street, or into your basement, then radials need
to be abandoned as your counterpoise solution.

That in turn begets the dire need for something counterpoise and efficient
that is not radials. That in turn begat the FCP, designed specifically to
minimize ground losses in far less space than radials.
