If anything it's frustrating that there aren't monopoles, because if there were, we could make the E and B equations symmetrical under interchange of the fields. It would be a lot prettier, and I think it would be easier to teach to undergrads.

How about a single equation instead ?

(or even just equations (3), which make symmetries more apparent)

I mean you could just do that and tell the students that the magnetic charge and current densities are always zero unless we eventually discover monopoles.
