Spinning enough to produce usable gravity is non-trivial and building something like that in space requires overcoming Earth's own gravity well.

- ben_w 4y agoNon-trivial yes; although house-sized spinning fairground rides are a thing so it's clearly infinitely easier than the gravity of Mars being a law of physics. And the only sane way to do this is ISRU, so we don't need to overcome Earth's gravity well for the structural mass.
