Einstein's theory is not all there is to science.

You say something about a quasar being one big star. Don't forget that there are other properties of a quasar to take into account, including its spectrum, its variability, its absorption properties, and the periodic jets that we see emanating from them.

For the galaxies, they also have totally different properties, much more complex than you would expect from reflected images. For example, some of them are elliptical in shape, some are disk-like, some are spherical, and some are literally broken in two. We also see galaxies colliding (and can model it with simple Newtonian gravity). In addition, they have complicated spectra that include emission and absorption lines, neither of which can be explained by reflected images. It's easy to tell when something is being multiply imaged because the spectra are basically identical. A redshift will not change the spectrum shape.

Finally, if the universe were curved at a distance of the galaxy, we could measure it. In fact, they might have been able to measure it a 100 years ago.

The problem with making these kind of hypotheses is that you don't have nearly enough experience to refute them. I'm not at all against thinking, but it's easy to get caught in a mindset if nobody is around to tell you otherwise.
