Yes but spacex didn’t promise anything physicists said is impossible. Engineers saying impossible is different from physicists saying it.
The equivalent would be if spacex said something that violated the rocket equation. They didn’t. And also while they promise the Mars, they can settle for the largest reusable rocket as a consolation prize. In fields like biotech and fusion there’s often no consolation prize. So spacex was well managed with the right level of optimism and practicality. Not so here.
