Apparently, they're right, since you do not yet know this fact to be true.

The Earth orbits the Sun. This orbit isn't a perfect circle; it's an ellipse.
Kepler found that out.

The Equation of Time reflects an Earth where apparent stellar circumpolar
motion... is regular like clockwork, but the elliptic shape of the Earth's
orbit, which supplies the difference between the daily cycle of the Sun and
apparent stellar circumpolar motion, causes sundials to need correction to align
with mechanical clocks.

Therefore, to explain the rotation of the Earth in the simplest terms, we
consider that its rotation should be judged relative to the distant stars
instead of relative to the Sun.

No doubt the reasons you have for thinking we shouldn't do this seem good to
you, but they are bizarre and make no sense to just about everybody else.
