Here's an EU/PC hater quote that I read recently for instance:
The concept of "quasi-neutrality" is meaningless in this context. You could say the same thing for an electrical discharge in the Earth's atmosphere.For scales greater than the Debye length the plasma is quasi-neutral and electrostatic forces between ions and electrons are zero.
https://en.wikipedia.org/wiki/Debye_length
According to the Wiki article, interplanetary space and solar wind supposedly has a Debye length of about 10 meters, so the (false) argument goes that it's impossible for electrical current to be traveling from the sun to various planets. Variations of this same argument are applied to interstellar and intergalactic space as well. This is easily shown to be patently false however based on *mainstream* studies of "magnetic ropes"/"flux ropes". Currents in plasma travel through Birkeland currents (aka "magnetic ropes", "flux ropes") which are not at all limited by the "Debye length" of various plasma in space.

And of course we've also seen magnetic ropes connecting the sun to Saturn as well.The discoveries include giant magnetic ropes that connect Earth's upper atmosphere to the Sun and explosions in the outskirts of Earth's magnetic field.

Angelopoulos estimates the total energy of the two-hour event at five hundred thousand billion (5 x 10^14) Joules. That's approximately equivalent to the energy of a magnitude 5.5 earthquake.

The distance from the Sun to Saturn is roughly 929 million miles so a 10 meter "Debye length" related to solar wind and interplanetary space is ultimately entirely irrelevant in terms of how far current can travel through interplanetary space, or any other type of plasma in space. The term "quasi-neutrality" is meaningless as it relates to the distance that currents can travel.
Current in space takes the form of "Birkeland currents" (aka "magnetic ropes") which can stretch between various objects in space, and various galaxies and clusters of galaxies in space.
The Debye length argument is scientifically irrelevant in terms of how far that electrical current can travel through Birkeland currents and how far it can travel between objects in space.
