That is actually the other side of the argument. When
an observer arrived after the game started, Cecil was
on third base. Using steady-state logic, the newcomer
assumes that Cecil is there without ever having to swing
a bat.

Someone looks at a transmission line during steady-state.
The source is supplying 100 watts. The load is dissipating
100 watts. The forward power is 200 watts. The reflected
power is 100 watts. The incorrect assumption is that the
source is incapable of delivering the 200 watts of forward
power and the 100 watts of reflected power. But the exact
amount of energy required to support those values
was provided to the transmission line before steady-
state was reached. It was rejected by the load and is
still there in the transmission line during steady-state.
