"RF isn't DC ... it doesn't just flow to the earth and disappear. It flows back and forth every half cycle."

That brought to mind the AC/DC power rivalry of the late 1800s. George Westinghouse, with a new AC power transmission system, went up against Thomas Edison and his original DC system. I seem to recall that one of the early arguments against AC was that it couldn't possibly deliver power since it would be returned when the current changed direction. I couldn't find a reference to that, but I thought I had read that DC was still used in parts of New York City well into the 20th century. Turns out that DC was ended there only in 2007!
