Intuitively, I have got to think a 200:1 mismatch is significant.

But consider a 9:1 mismatch using 450 ohm feedline. The impedance
at the current maximum point on the feedline is 50 ohms.

So what is the loss at the antenna/line junction? I understand matching at
the transmitter end. I understand using low loss line. I don't understand
why the mismatch at the antenna junction is ignored.

It's not ignored. It is taken into account by the losses in the feedline.
The power reflected by the antenna is not the antenna's problem. It is the
feedline's problem. A two ohm copper or aluminum antenna is probably very
efficient. It is just hard to feed directly.
