I emailed Viktor Blasjo, an expert on the history of mathematics and physics on this post. I quote:
Very nice, but the author neglects another strong argument: how Aristarchus’s own treatise on the sizes of the sun and the moon suggests physical support for heliocentrism. See pages 86-88 of https://arxiv.org/abs/2102.06595.
Thank you! I had never thought that Aristarchus might have intentionally seeked a lower bound for the relative size of Sun and Moon. This does indeed make a lot of sense.
