Here's a physical analogy. We light a butane lighter at one
point and observe the flame. We close the lighter and move
to another point 100 yards away. We light the lighter again
and observe the flame. Did me move the flame by 100 yards?
Or did we convert energy into power at one point, then
move the energy source to another point and convert the
energy into power?

If you move watts of power then you should be able to
measure that movement in watts/sec or joules/sec/sec.
Have you ever measured such?

My Bird Model 43 Instruction book says:
"---designed to measure power flow and load match in 50 ohm coaxial
transmission lines."
I`ve used it many times.

Would you agree it is indirectly measuring joules/sec
not watts/sec? That would be energy flow.

actually, its not measure energy or power, its measuring voltage and current
and presenting you with the result of a calculation that represents power.

Like I said, it is indirectly measuring power -
by sampling the voltage and current at a fixed
point in a known Z0 environment and performing
some in-phase and out-of-phase phasor additions.

The point is that it is displaying watts at a
*fixed* point, i.e. average joules flowing past
a fixed point in one second. It is the joules
that are flowing, not the watts.
