That's already assuming that everywhere in the universe is homogenous. E.g.,
if we see a galaxy to the north that is halfway to the "edge" of the
universe, you're assuming that if someone in that galaxy looked north, the
"edge" of the universe would be the same distance away, rather than much
closer.
I've seen discussions about the density of galaxies at distances, and how
they don't match what you'd expect if the universe was expanding. But they
do match what you'd expect if the universe was homogenous on a 4-sphere (or
maybe a 5-sphere?) and time was simply running slower farther away because
the normals weren't parallel. I.e., nothing's moving. It's just going slower
from our point of view because it's closer to the horizon as seen by us. Of
course, that's still homogenous, but does it really need to be?

Yes, we're traveling together,
but to different destinations.
