I can only quote Einstein (once again) for you:
"Everything should be made as simple as possible, but not simpler."
You have ignored Einstein's advice and "uncomplicated the matter" to
the point of violating the laws of physics. When you use the
distributed network model for part of the circuit and then switch, mid-
stream, to the lumped circuit model, you are indeed violating the laws
of physics (as I have pointed out to you before). But you are
certainly free to delude yourself into ignoring reality and choosing
to commit technical suicide in the process. When you switch to the
lumped circuit model, you are presuming faster than light speeds and
completely ignoring the existence of EM waves. The fact that an EM/RF
signal cannot travel even one inch in zero time simply cannot be
ignored. If you take that one inch speed of light delay into account,
hopefully you will realize just how technically confused you really
are about the magical reversal of cause and effect concepts that you
are promoting.
