Why don't spaceships rotate to cause artificial gravity? (discuss.tchncs.de)

We all know the pictures of the astronauts on the ISS floating around. We also suspect that a lack of gravity is bad for the body as the muscles go weak and such.

Why don't spaceships just rotate to cause the effect of artificial gravity through centrifugal forces?

There was recently a "design proposal" (more of a published thought experiment) I read (posted on lemmy) where the authors had figured out the diameter required such that the gravity differential from feet to head wouldn't be weird. It was quite large if I recall.

    I guess thats why, in sci fi it's only used on ring shaped objects. A ship with a ring around its mid section, or a space station, or the expanse has a barrel shaped ship.
