It might help if the language was made more understandable. Isn't the
problem in getting an absolute ground reference point at the end of
the dipole? It is possible to model a 3D antenna with a 4th dimension
ground "plane".


Nope, that's not the problem. The language I am using is standard. To
understand it, get out your multivariable calculus text, if you've kept
it, or go to the library and borrow a good one. (Shameless plug: Howard
Anton's Calculus book is a good one -- I helped debug it before
publication.) Look up "independence of path" in the section on line
integrals, and look up the related topic of "conservative vector fields".
*That's* the problem, and not anything about ground references. What Roy
is talking about is an important special case of lack of independence of
path; there are many more examples.
