On the contrary, if one assumes same-cycle reflections, the reflection

Why wouldn't it, indeed.

if there are no components that introduce a time delay it would.

All real-world components introduce a time delay.

so no
transmission lines allowed... hence no reflections. and you are back to a
simple lumped resistor problem.

RF energy travels at the speed of light. For the length of time it
takes for the energy to reach the resistor and reflect back to the
source, the source sees 50 ohms. That length of time is not zero.
