Some electrostatic speakers use a material with extremely high surface
restivity for the diaphragm (made e.g. by lightly rubbing the plastic

Yes, I have heard that. But why approximate it when you can achieve it
explicitly through design?

I suppose there could be some advantage to using standard off-the-shelf
amplifiers.
