Booty',
I'm afraid Walt has a couple of things in that sort of backwards, or at least 'not right'. The first thing is the premise that a 'perfect' ground is zero resistance and zero reactance, which it isn't. I've never run across having to 'add' resistance to a 'ground', and have never heard of anyone else having to either. It's always been the other way around, getting rid of some resistance/reactance.

If there is always zero resistance on one of an antenna's input terminals (and there are always two of those thingys) there can be no radiation from that antenna. So if a 'perfect' ground means there is no resistance on one terminal it also means that antenna isn't gonna radiate, so is a 'perfectly' terrible antenna. That doesn't make a lot of sense, does it?
To make it just a little bit more fun, since RF is AC, it means that the (+) and (-) parts of that signal switch 'half's of the antenna they go to once every cycle. So, half the time that (-) 'ground'/radial system is the radiating prtion of the antenna and that vertical part is the 'ground'/radial system. Wait! There's more fun. It also means that if you send current into that (+) part of the antenna, then there has to be current coming out of the (-) part of the antenna. Otherwise, no radiation.
Mixing AC characteristics with DC characteristics just doesn't work, gotta think of each in a slightly different manner. I think Walt may have miss-thought part of his ideas.
