How is Olber's paradox a paradox, when stars do NOT go on forever, but are grouped into sparse finite galaxies?

>do NOT go on forever, but are grouped into sparse finite galaxies?
If the galaxies go on forever then so do the stars. Grouping is irrelevant.

Pass whatever you're smoking, now. I need to see this hidden qualia.

Replace stars with galaxies and it's the same thing.
But it's already obvious at this point that Universe for sure is not static. It could possibly be infinite still, but the expansion of the universe which is faster than light creates an event horizon. That's why what we see is called observable universe.

If there are finite stars/galaxies then the paradox is resolved. It was posed against early modern models of an infinite eternal universe caused by applying Copernicus (homogenous universe) to Plato (eternal universe): if the universe were also infinite in size then the night sky should be bright because there would be a distant star (or galaxy) at every point, indeed infinitely many stars/galaxies at every point.

Galaxies end soon in red shift.
