Has anyone bothered to write your counterargument in more detail? I think I understand your argument but I wonder if anyone's really done the calculation... though I suppose the conservation of momentum itself a theoretical proof that the "other forces" have to cancel out. Is it possible that classic electrodynamics are not wrong, but there's some other fundamental thing in play here? I'd be a bit surprised, given that this just seems to be such a simple setup, but maybe? One can dream....
