You will note a problem here. Since the Earth is made of proton and
electrons, then a tiny charge asymmetry will produce a net charge of
one sign, as you say. However, the Moon is also made of protons and
electrons, and the same charge asymmetry will produce a net charge of
the same sign as the Earth. In your scenario, the Earth and the Moon
would then have the same sign of net charge, and if you recall
Coulomb's law, like charges repel. Thus you would predict that the
Earth repels the Moon, not attracts it.

To account for attraction via Coulomb's law, you would have to explain
how it is that the Moon and the Earth acquire opposite charge.
Likewise, you would also have to explain how the Sun and the Earth
acquire opposite charge. You will also note that it is difficult to
arrange the Sun and the Earth and the Moon all to have opposite
charges, so that at least one of those pairs would have to repel each
other, which is counter to experiment.

I think this recent post by Mitchell Jones neatly explains how an
electrostatic force generated by a slight difference between the
attraction of opposite charges versus the replusion of similar charges
can produce a gravity-like force. This isn't due to an imbalance
between the charge ratios of electrons/protons that would lead to an
overall imbalance of charges, but rather a difference in force when
considering the attractive force versus the repelling force generated
by charges. This is a pretty straight forward application of Columbs
law.

I used to think that there would be a net charge that generated the
field. A net charge does exist due to electrons blown off the Earth
and this generates the electric field, but this is not the main
mechanism behind gravity.
