Basically not at all. The brightest things in the universe easily outshine whole galaxies despite being star size or a bit larger. Andromeda is only 4 million light years away but it’s too dim to see without a telescope. Can’t get past the inverse square law.

Your main point is correct, but you can see Andromeda with the naked eye on a clear and dark night. It is 2.5 million light years away and It is the only spiral galaxy (other than our own) visible to the naked eye.
