By this line of reasoning almost all past theories can the discredited. People use a theory to make predictions and act on them. Only later do you learn the shortcomings. If you don't have empiricism you don't even have a tool to systematically notice your error. I think this is a fully general counter argument.

No, the important older theories lead to better theories.

Newton's gravitational physics made correct predictions of limited precision, and Newton's laws lead to the development of Navier-Stokes, kinetic theories of gasses,etc. Even phlogiston lead to the discovery of oxygen and the modern understanding of oxidation. You don't have to be 100% right to make useful predictions.

Vitalism, on the other hand, like astrology, didn't lead anywhere useful.
