We address three issues. i. The point particle assumption, inherent tonon-quantum physics, is singular and entails divergent fields and integrals.ii. In quantum physics EM plays an asymmetric roll. It acts on quantum wavefields (wave functions) but the wave fields do not react back. We suggest topromote the one sided action of EM on quantum fields into a mutualaction-reaction partnership. By so doing, the quantum wave shares itsanalyticity with the EM field and removes the later's singularities anddivergences. iii) The conventional U(1) symmetry leaves quantum dynamicsinvariant under a 'general' Lorentz gauge and impose the standard minimalcoupling of the quantum wave to the Em 4-vector potential. One, however, hasthe option to ask for in-variance under the 'restricted' Lorentz gauge. This inturn invites in a coupling to derivatives of the vector potential in additionto the minimal coupling and, so to say, enlarges the U(1) symmetry. We findthat the electron exhibits distributed charge- and current- densities. Theenlarged symmetry is expected to bring in its own constant of motion. Indeed itdoes. 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 QEDformalism.

Three arguable and interrelated concepts: point particle singularity,  asymmetric action of EM on quantum wave functions, and the Left out  restricted Lorentz gauge from U(1)
