I agree that drugs would have a hard time solving freefall problem, but that's just because it's the wrong tool for the job compared to genetic engineering which is hardly superscience.

Genetic engineering has yet to adapt a complex animal to live in a completely unnatural environment. The more we study genetics the more complex and interconnected it gets. I just don't see such major and fine tuning being anywhere near as "simple" as modern science fiction assumes.

The hassles of the average are not the same as the super fit heavily tested. There's a reason why even after long term tests of drugs weird rare problems pop up.
