Are you suggesting that an

infinitely long to read steady state?

Your infinitely long open-circuited transmission line example
certainly takes infinitely long to reach steady-state so the leading-
edge EM wave continues forever with zero reflected EM waves and your
argument involving reflected waves falls apart.

Your finite open-circuited transmission line example reaches DC steady-
state where EM waves cease to exist so your argument involving forward
and reflected waves falls apart.
