  We address three issues. i. The point particle assumption, inherent to
non-quantum physics, is singular and entails divergent fields and integrals.
ii. In quantum physics EM plays an asymmetric roll. It acts on quantum wave
fields (wave functions) but the wave fields do not react back. We suggest to
promote the one sided action of EM on quantum fields into a mutual
action-reaction partnership. By so doing, the quantum wave shares its
analyticity with the EM field and removes the later's singularities and
divergences. iii) The conventional U(1) symmetry leaves quantum dynamics
invariant under a 'general' Lorentz gauge and impose the standard minimal
coupling of the quantum wave to the Em 4-vector potential. One, however, has
the option to ask for in-variance under the 'restricted' Lorentz gauge. This in
turn invites in a coupling to derivatives of the vector potential in addition
to the minimal coupling and, so to say, enlarges the U(1) symmetry. We find
that the electron exhibits distributed charge- and current- densities. The
enlarged symmetry is expected to bring in its own constant of motion. Indeed it
does. The anomalous g-factor of the so designed electron emerges, up to order
({\alpha}/{\pi})^2 as the new constant of motion but, without invoking the QED
formalism.
