E-beam does not need to be born in the plasmoid. Any region of strong electric fields near the pinch region can generate runaway electrons. Most observations suggest that the runaway electrons are generated in low density regions outside what LPP calls the plasmoid region. If this observation remains true, you still have a runaway e-beam problem and the x-rays that go with it. This assumes that a plasmoid can confine all the electrons as the theory under test describes. Again, LPPs recent results suggest that the plasmoid has yet to confine electrons as the x-ray spectrum was very hard; much harder than a 140 keV thermal spectrum suggests. I can’t speak to the theory in detail but the experiment seems to disagree with the theory up to this point.
