Your arguement is similar to the chicken and the egg syndrome. Science
assumes charge exists because of matter. Namely because we have
declared it only exists in matter. Not an unreasonable assumption based
on simple observations. (we see it hanging around matter) Charge polarity
infers two observatinal points and material bodies at each to communicate
a differential. (THIS IS ALL IT ASSUMES) Polarity infers electrodynamic
action also, as something has to react against something to indicate to
an observer, a polarity, a differential. Thus, if a naked charge exists
in space, any other person measureing it would automatically assume the
opposite charge potential.
A charge about an isotropic capacity (single object) in a vacuum does
indeed exist! The opposite charge need not reside in the immediate
vicinity! The opposite charge is confined to the rest of space. Work
was done on the vaccum to separate the charge at some time in the past or
it would not be there. The work was done, usually elecrodynamically, but
could be done mechanically. It involved two bodys of matter at one time
or another and a source of energy. In a metallic circuit, needed to
determine charge quantity or polarity, we have our nice little material
electrons to commute the charge about (even though they never really
move) and make it do work so our eyes can see what is there.
CAHRGE EFFECT is trundeled about through conductors by the good office of
electrons which do little real movement! Electrons can't just be rammed
into a metal lattice by the hundreds of trillions! Charge effect can be
transferred very rapidly though through the material. The material
particles in matter likewise allow the charge via coulombic forces to
react against matter also.
Charge itself might well be free of matter and not inate to it. It is
definable to us only with direct interaction with matter which are a
bunch of atomic and molecularly locked charges in a lump. Charge implies
potential energy only in the presence of matter! I am not rewriting the
book on electrostatics, just wondering if the whole business isn't a
matter of perception. I, unlike many, don't need to profer a theory to
wonder about the way things work based on my own observations and
thoughts about the possible interactions.
Finally, if something is massless, acceleration itself has no meaning and
is an absurdity, and thus no force and no energy could result from its
motion at supposed super-luminal speeds. The moment matter interacts
with anything, light velocity and our material perception is the limiting
factor.
