IMHO the concerns that people won't be able to handle the rotation are under tested. While I'm sure there are people who won't be able to handle it just like there are people who can't put on VR goggles without barfing, I suspect the average human could tolerate it just fine.

I would love to see a pair of Starships hooked together with a sturdy cable a couple of dozen meters long and then spun around each other to simulate gravity.
