Just as a mental exercise, assume that the entire setup...van and
antenna, is transported to a place in space where there is negligible
capacitance to the earth.

Is it your contention that the setup would operate any differently?

And if the van/antenna had been constructed on another planet before being
sent into space, is the earth still required or just the other planet?

Each piece in the space is neutralized by the rare plazma.
