Let's assume you are correct. Here are a few questions:

1. Given a 90 degree monopole fed against an infinite
ground plane, what would be the phase at the top of the
antenna compared to the phase at the feedpoint for any
instant in time?

2. Why would the feedpoint impedance of a 1/4WL monopole
be more than a magnitude less than the feedpoint impedance
of an infinite monopole?

3. Where does the above current go when it hits the open-
circuit at the top of the monopole?

4. Why is the total energy in the E-field at the top of the
monopole so high?

In what way are any of the questions relevant to, or deterministic of
the assumption?
