Yes?, but see below- endless lines expanding? uh uh

You have gone to some trouble here, and I appreciate your input, but
in order to not repeat myself, I will try to reply to George in detail
(but of course, still feel free)

Tie your rubber band to my nose. Start to stretch it, and if I could
maintain a view of the whole, your diagram (and Georges) stacks up.
But I can only see F (end of band) as it was BEFORE stretching. At
that time it was travelling at 3000km/sec (distant red shift). You are
taking the view that I can still see ALL OF the band at once, now.
