It is not "logical coninuity" that forces us to borrow from tomorrow. It is
the practice of defining Coulomb before defining Ampere. Do you agree that SI
is not compatible with the sequence we use to teach electricity? People who
introduced SI created a problem which we should recognize. Using 4*Pi*eps
(or 9*10^9, for that matter) is antipedagogical. I know it will not be easy
to create a better sequence but somebody should try. Recognizing need for a
change, and expressing it loudly, is useful. It is our physics.
