I thought that my counter example was quite clear -- You and R. Hull
claimed that "One coulomb of electrostatic charge has the potential
for vastly more effective work than one ampere flowing in a circuit."
I provided an example where this is obviously and provably not true.

Not necessarily. Neither charges nor currents _by themselves_ determine
the ability to do work.
