Water As Shielding

If we finally determine how to prevent bones and
muscles from deteriorating in free fall, we can then
make space colonies as non-rotating structures and
that opens up a whole new environment, such as hollow,
rocky asteroids with low tensile strength. Cheap
enough that small groups could settle such bodies,
since they wouldn't have to add structural strength,
etc. Just remove some material, air seal the rock and
set up house keeping. Then we'd have some really cool,
cheap alternatives to the space cities, that your
average malcontent could colonize. With several
million asteroids in the asteroid belt, we could have
every imaginable society, as well as space pirates.
How many stories could be written with this option?
