Assume a one second long lossless unterminated transmission line.
Pour 1000 watts into it for one second. During the next second, we
disconnect the line from the source and you grab the two wires, one
in each hand. Then tell us whether reflected power exists or not.

So if we had an infinitely long antenna, would the power put into it
last forever?

It would have a feedpoint impedance of around 600 ohms and I
don't know how long it would have to be to eliminate reflections.
A terminated rhombic comes close to the characteristics of an
infinitely long antenna.
